Great hidden gem in DC, inside is cozy, outside patio is perfect for the summer to grab a drink with some friends. Menu is balanced, but stay away from the tuna sushi appetizer- tiny dish about 1/4 the size of a normal sushi roll and beet salad lacked flavor. Would still go back given the ambience and service.

My 18-year-old son and I were visiting DC this past weekend, and stayed in the Kimpton Mason & Rook, so we also wanted to try the restaurant fare. We ate inside, because it was pretty crowded out on the patio. I was disappointed at the indoor seating, because they only had the high bar top tables, where I feel a bit unstable due to having vertigo. The other seating choice was a loveseat with a coffee table in front of it, not conducive to dining. Our waiter was very polite and helpful, offering good insight and suggestions for our feast. Sadly, he was called away to lift heavy items and was replaced with another waitress. She was also very helpful, engaging, and friendly. We tried the kimchi pickles as an appetizer, and it was our favorite part of the meal! My son ordered the lamb belly tacos, which he said were so salty that he couldn’t eat all of them. I ordered the fresh beet salad, which was delicious. I also ordered some spicy tuna, which I ended up sharing with my son because of his tacos being too salty. Overall, it was a decent dining experience, despite the uncomfortable seating. I’m a bit spoiled by the restaurant at the other DC Kimpton hotel, the Donovan. That was a much more upscale restaurant, with similar pricing but better food.

Check in was easy and the hostess was pleasant. I loved the happy hour options. The waitress was not very attentive although we enjoyed our meal.

Very disappointed
After seeing reviews - I expected much more. Food was fair. Wait staff pleasant but I'll informed or just not into job.

Delicious drinks & food - everything was very good. The Brussels sprouts with dried peaches were amazing. Nice seating outdoors. Service was friendly but slow.

Radiator was a surprisingly great dinner in DC. The ambiance of the outside seating is cool, with a ‘rooftop’ feel, even though it sits the ground level. Food was awesome (definitely recommend the Amish chicken), and the house cocktails were unique and worthy of the price tag . Service was great too! Highly recommend!

The cocktails were well crafted, but the rest of the meal and service was not pleasant. There was only a handful of tables that had customers but we ended up waiting almost 45 minutes for our meal. The server was nice but new, her first day actually. The meal would have been tasty but all three of our meals were terribly over salted. We tried to eat them because we were so hungry and let our server know about the problem. She did go back and talk to the Chef and they reduced our bill by the cost of one meal. We would not go back to this restaurant in the future.

The service was fantastic! Jeff really hooked us up with brunch drinks, and the food was high quality

We waited 6-7 minutes for someone to come to the hostess station. Once we were seated, we were never seen by a server. No silverware, no water, no hello. We waited 9 minutes before leaving.

Threw me at a table that felt like I was in a closet.

The atmosphere is casual and yet feels alive - we loved sitting outside. The server was friendly, and offered helpful suggestions. We loved the appetizer tots and the burger.

This was by far the worst Open Table experience that I have ever had. The restaurant was a third to half full when we arrived and remained so for the rest of our visit.

Our server seemed disinterested/bored and admitted to forgetting our drink order. A second server took our food order. It took over an hour for our food to arrive and it was not the correct order.

My brussels sprouts were charred beyond recognition without any hint of cashew or yogurt. My salmon rillettes turned out to be a cream cheese based dip topped with a quarter inch of olive oil for good measure. There were no obvious signs of salmon. The kitchen had run out of lavash and they substituted slices of country bread that were burned to a cinder.

I will not be back.

Enjoyed the food... especially the appetizers. Great service and nice atmosphere.

We had reservations for 4 and the host quickly adjusted for us 5 and we had a cozy spot on a cool u-shaped leather coach. The happy hour specials are great and at $5 for a Glas of bubbly and wine nothing to complain about as we were waiting for everybody else to arrive. Yes, we were seated without having to awkwardly wait for everybody to get there like at other restaurants. Nice! Our waitress was fantastic. Super friendly and bubbly and she made she quickly took our orders got us replenished an out in time for our play. Some of us had a series of apps - bacon fries anyone - and others entres. I had a the purple sweet potato gnocchi with kale, onion and labneh and they were phenomenal. Nice different take on an ubiquitous dish! Everybody else enjoyed theirs as well and we have been telling everybody about Radiator because of this.

The service just was not up to par never gave us any clue on quantities of the appetizers we had ordered after appetizers we decided to go somewhere else for dinner since the service was not up to par ordered an old fashion with no squeeze or orange rind inside the old fashion it appeared there wasn’t a lot of love that went into taking care of us tonight I am never this way when it comes to reviews but I think you should know that it was just Idiocracy at best waitressHad zero knowledge of menu and kept referring to her full-time job as a bartender during the day not a warm and fuzzy feeling when you’re there to drink at y’all’s place and have an incredible time we did 12 months to go and a little disappointed after all that time but will give you another chance when Sarah is working knowing I will get top-notch service

Danielle is the best!!! Yummy food : )

Great place and great brunch. Overall, a good experience.

Exellent food and drink

Noise level was high for a Wednesday night, made it a little hard to talk. The food and cocktails were fantastic!

We met up with some friends on April 1st for Radiators "April Mules Day" half price Moscow Mules promotion! It was a lot of fun in a new, elegant and trendy setting. They had about 8 varieties of Moscow Mule... we tried the Sailors Mule (rum based) and the regular and they were delicious. Service was super slow on the drinks, but our very lovely and fun server, apologized and explained that it was a new thing they were doing, so the bartender was still finding her rhythm. When they arrived, the drinks were garnished with Easter eggs which had different prizes inside. We snacked the Bacon Fat Fries and Cheese Croqueta's which are a MUST when you're there - you will relish every bite! The lamb taco's are also very yummy, as it the chacutterie platter which they added cheese too (nice but pricey for the quantity). The staff were all super friendly. Dying to go back so we can try the beautiful outdoor patio.

I was a bit skeptical of booking a reservation for brunch at Radiator since it was Easter Sunday and unlike the vast majority of DC area restaurants, Radiator had open availability. To my dismay, I was pleasantly surprised. The food was delicious, and the drinks were even better. However, the service was absolutely terrible. We had to walk around the restaurant in order to flag a someone down to be seated. Fortunately, one of the bartenders ran out to assist us. Yet nobody could find the hostess. When we located the hostess, she didn't immediately sit us down instead she seemed confused. By the time we sat down, we had to find her again to get menus. Then she sat us in an awkward corner although the entire restaurant was empty. We were relieved when her shift ended because we were given someone who rescued the rest of the day. Unfortunately, I still give the place 1 star for service.

Came for Easter brunch at 915. We were seated after a short wait. Minute 15 we were greeted and gave drink orders. Minute 35 we were finally given water. Minute 45 we were told drinks would be another 5 minutes. At this point we decided to brunch somewhere else.
I have had cocktails and snacks here once before and was excited to try more of the menu, however, the service was not on point that day. Note, we were the only table seated in the dining area.
I’m hoping our future visit will be better.

Overall Brunch was a good experience. The entrance to the restaurant is hard to find. Service was slow when we were first seated but it got better. This is a hotel restaurant. The outdoor area was cute but was closed.

Give it a solid B. Everything was pretty good, but there wasn't anything that was amazing enough to make me recommend to others or want to go back. We really enjoyed the deviled eggs, kale salad, short rib ravioli and gnocchi. Our least favorite dish was the octopus so I would recommend not getting that.

Visited 2p Sunday and expected a tapas menu, but it was only brunch. Sat for 10 minutes before saw waitress. Food, drinks, and ambiance were good.

Squid was great!

Really interesting & delicious cocktail menu but the food portions were disappointing. Charcuterie was not good, do not recommend. Gnocchi was amazing but not filling. After a very expensive dinner we had to go get more food somewhere else.

Just one word - Amazing! Food was delicious. Would come back again next time in town.

Back room is dark and isolated and the bar area, crowded, noisy and uncomfortable, unless you have a big party to be seated at a very few, more comfortable tables available. We we're sitting and waiting for a long time before anyone came over to take our order and that was when I stopped one of them to see why we were not getting any service. The Manager was very nice and helpful.
Overall, ok for meeting friends for drinks, not for a quality sit down dinner.

We ordered a mocktail, which was delicious.. But our waiter couldn't tell us what was in it. And didn't bother to find out.

Great place for drinks and tapas. Staff are very friendly.

Great service each time I go and they always have specials on their craft cocktails, which are well-done and balanced (and I don't say this easily). Love the outside fire pit and overall ambiance. Big Thumbs up!

Just had drinks at the bar this time. The two female bartenders were GREAT!!

good cocktails and ambiance. It's never been really crowded whenever I've been so you can still hear each other/have a conversation. The booths are comfy and spacious. food is good too (I've had the short rib ravioli, lamb gnocchi, lamb tacos, and radiator burger. Portions are a bit small though (only 3 raviolis in short rib dish for example) so either don't come hungry or order apps in addition to entree.

Food was great, jeff was awesome bloody Mary’s were on point steak and eggs....yes. Lemon pancakes yes.... what more......

An otherwise great evening was totally spoiled by a waitress with a terrible attitude, we didn't feel welcome and felt as though our presence was an inconvenience to her. Frustrating, as the cocktails were tremendous, and the menu very unique!

Food was delicious! Chef Dearden has a great menu to explore! The crab beignets were great. So was the duck and grits. Drinks are great as well. My party had a great time at Radiator for brunch. Can’t wait to go back.

What a waste of time. We went there last minute for Xmas Evenings dinner. It was dead. When wanted to order off drink menu, was only allowed to order off special drink menu. The food that was cold. We didn’t bother complaining, our waiter was no where to be found. The only saving grace was that was out to dinner with my husband and we enjoyed each other’s company and not having to fix dinner.

This is my second time here and once again, the food was amazing! Our waiter (Jeff) was excellent and timely! Definitely try the duck and waffles - it's the best!

So mediocre. The server was attentive, but drinks and food arrived with great delay. The server could not explain the dishes (nor could we explain the “cornstarch” residue on “bacon fat fries”. ) In general, it’s a hotel bar fit to hang in to wait for a ‘date’ to come get you. NOT A RESTAURANT.
