Radiator

Wow! What a nice find tucked away inside the hotel Mason & Rook. Low ceilings and nice decor, has an initimate feel. Good happy hour selection and prices on bar snacks. The drinks from their “signature” list were OK but not spectacular.

Our server was attentive and helpful. Alll and all Radiator exceeded expectations.

I was not very hungry so I shared a salad (v good) and had 1 small plate (eh). My friend had bucatini and didn’t comment. We were very comfortable eating at the bar and service was excellent. I’d go back if staying at the hotel.

Food was great, service was not

Every dish we had was delicious! Great for brunch with friends.

Waaaay overpriced. $8 for a pot of coffee, $5 for juice, $30+ for breakfast entrees. Plus an 20% gratuity and an $8 delivery change to a room upstairs. Creative food, service was absent. Bartender was super aloof and unfriendly too. Liked the music they played though. With so many neat places nearby, they’ll have to do better than this.

Very much enjoyed our meal. Highly recommend their short ribs, and spaghetti I squash carbonara. So delicious, great options for keto folks.

Fabulous! Food was terrific, service attentive and gracious, location - love Mason & Rook.

Overall sub par experience, waiter was trying best but neglected orders and extremely slow. Had called prior to confirm and was hung up on.

Lovely intimate space, great bar and comprehensive selection.

Food was excellent, with great service. Outdoors was not available, but it looks comfortable, with a nice atmosphere. . Inside was noisy.

Food and cocktails were amazing but had some of the worst service ever. Took 25 mins for anyone to come by the table to ask for a drink or app order, then forgot about it. Had to flag down other staff to order, get refills, and the check. Absolutely unacceptable service.

Excellent service! Delicious food. Our party had lobster tagliatelle, scallops and burger.

Great food! The sea bass, eggplant and wagyu steak were good with great flavor. Drinks were excellent and the waiter, Mike, outstanding!

Wonderful cocktails and the service was great! The only knock was the burger I ordered, which was a little on the salty side. The small plates more than made up for it, though!

Great burger, beer and shot.

Server was not attentive, we never got water after the first pour, drinks took 30-min to arrive, food was cold, and standard accompaniments (straw with a smoothie or syrup with pancakes) had to be asked for or gotten from the bar. There were two large tables in an otherwise not busy restaurant but there were plenty of servers. The food for the larger table was actually delivered when we were leaving so there was no excuse for the service. Manager discounted drinks but experience was neither relaxing or pleasant for a Sunday brunch. Won’t be back soon.

Drove from Rockville to this location to entertain friends and my dog and we were not disappointed. Menu selections were excellent, dog friendly and the outdoor ambiance was amazing. Good service and the food & drinks were great. We will be back!

We went for breakfast. Order the lemon pancakes and don’t look back. They are amazing. Bright, fresh and light as a cloud. The maple ginger butter melts right over them and gives them just a touch of sweet and heat. So good! Bacon side portions were generous and the coffee was steaming and strong. We sat in the courtyard which is nicely tucked off the street.

Service was not the best. Porch chop eh. But loved the burger.

Food was really great. Service was good too. Would recommend the Wagyu beef. Good cocktails

Service was fast and friendly, food was tasty, specialty drinks were amazing, good music selection, and overall a great experience for our team dinner. The ambiance was beautiful and energetic. I see this becoming a go-to location for future team dinners.

The vents smelled like old fish. Our waitress was so good

Food was great and service pleasant, though waiter disappeared after our entrees arrived. The only things we didn't like were that there weren't any fans/cooling systems on a sweltering hot summer day. The heat made everyone on the porch a bit testy and one of the servers (not ours thankfully) sprayed deet on herself twice right in the eating area, and the smell and chemicals wafted over to our table - ick. Overall we would say the service outside needs more oversight by management. Otherwise hotel staff was gracious and food inventive and tasty.

Our family was visiting the DC area and we decided to try out Radiator. We were very pleased with a quiet booth away from all the noise but we were disappointed with our server. The food runners were more attentive than the server. We enjoyed our food and drinks along with the nice private booth. My other concern was when we asked about the tree nuts for dessert the server said my daughter would be fine. The thing is they have pistachio ice cream which could have cross contaminated but the food runner assured us that separate scoops are used. They also brought sprinkles on the side separate from the other toppings.

Shared some of the small plates; each was tasty on its own but the textures were much the same.

The food was not bad, however the brunch menu had been paired down. The best part of the experience was the fact that we could sit outside and it was not noisy. The service however was awful. Getting even a glass of water was tough and after asking 3 times never got my glass refilled.

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.
