Catalyst has a very elegant, modern aesthetic that fits Technology Square very nicely. Every single item on the menu looked delicious and it was tempting to try everything. A must try: the "undecided" cocktail, where the bartender makes you a custom drink based on your favorite flavors.

Server (Cassidy?) was nice and friendly. Food took too long for how mediocre my entrée was, which obviously isn't her fault. Overall, not the best experience but would definitely give this place another shot.

There were maybe 15 people in the restaurant total, and our 2 entrees took an hour-twenty to come out. My Catalyst burger was pretty meh. Inside was medium rare (perfect) but the outside was hard and blackened, not at all to my liking. The toppings were also pretty underwhelming. We also ordered a pasta dish that was extremely tasty, would rate 5/5. Potato puffs and focaccia were also delicious.

Had a $16 cocktail that was tasty but barely larger than a shot glass and probably half as much alcohol.

Patio looks great, but unfortunately it started raining. The atmosphere in the restaurant was also very nice.

Nice place! Expensive. I've enjoyed dining both indoors and out.

The restaurant was lively, the staff was AMAZING - Carlos and Rigoberto were on top of things the whole night, and the food was delicious! Highly recommend this restaurant if you’re in the area. There’s indoor and outdoor seating, the cocktails are inventive, the service again - especially coming out of Covid - was really good. Kudos to the Catalyst team!

Very nice atmosphere, but that was the highlight. Although our food looked great, our entrées came out only five minutes after ordering, certainly not enough time to cook chicken and salmon. Both dishes were obviously cooked beforehand, and just warmed up. They cooled off quickly and tasted like airplane food. The salmon was very fishy. At these prices, you would expect much more. The place was almost empty, so there was no excuse for the inattentive service, but that could’ve been just with our particular server.

The food was terrible. We got truffle aioli and it tasted like lemon. We asked the chef if they may have confused the truffle aioli with lemon aioli and they said no. I would never recommend this place to anyone.

Service was good though!

My fiancée and I went to Catalyst and sat at the bar. They have an excellent spirits program and we enjoyed lively conversation with the bartender, Jay, as well as some of the other guests sitting near us. It is a beautiful space with a large outdoor area, as well as a fireplace which me made note of for future visits. They have several interesting cocktails using unusual ingredients. The food was excellent: we had the chicken liver mousse and split the bolognese. I had the baked Alaska as well, which was really great. The only thing that causes me to mark them down is there was a long delay after our initial drinks where we were not offered another. It was getting busy in the restaurant and at that time there seemed to only be one bartender serving the whole establishment. It was not like he was ignoring us, he was just very busy.

The quinoa salad and fish tacos were outstanding and the service was perfect. This was a business lunch.

Great place for dinner after work

I’ve loved Catalyst for years, but last night is making me rethink that. I hope it was just one very off night and not the new post-Covid status quo.

Service was non-existent. It took over an hour to get two burgers, both over-cooked and one with the wrong side. Add the incredible noise in there, and you’ve got a lousy evening.

Instead of giving unqualified raves to friends, I now have to wave a caution flag.

Slow night and made for excellent service. Food well prepared

Good overall experience. It was a little slow, but not our server’s fault, as he was the only one working our whole section.

A perfect setting for a business meeting or social event with quality food , well prepared. A bit disappointed with lemon curd tart as was more like a "flowing lemon liquid" not cooked!

Outstanding on all levels. Food and ingredients crazy delicious and fresh. Chef owned and you can taste the passion and love! I think this is the best restaurant in Boston/Cambridge!!

One of the best meals I have had in a long time. Service was great! Glad they are reopen!!
Will be back

We started with The Undecided cocktail which was absolutely delicious. We then shared an app of bruschetta. My friend had Bologna’s & I had a cavatelle. We shared a dark chocolate fondant, for desert & were extremely satisfied with the entire experience!!!

Staff was excellent and helpful. Food was good, just a bit expensive. Do recommend going all the same.

We ate outside on the patio - service was excellent from Carlos. We had 7 different dishes (including appetizers) and all of them were very good.

Food was great. Outdoor setup is pleasant. Service was attentive. Really enjoyed ourselves. The hamburger is a treat.

Despite being short staffed the existing crew did a fabulous job on a busy Saturday evening. Food was excellent; Drinks were a little pricy; but, we will definitely return.

Cocktails, wine and food was absolutely amazing. Every part of my chicken entree was cooked perfectly and the flavor was phenomenal. Sitting at the bar with Jay is highly recommended!!! Cant wait to go back

Great meal! Loved all of the super fresh and seasonal menu options. Highly recommend!

The venison and pickled persimmon salad I saw online was not available to order. I was fasting for Ramadan and hoping for a quiet dinner at sundown, but very noisy and obnoxious biotech individuals were having loud discussions. I would have preferred elevator music to their cackle. For the price and the selection, the experience was somewhat painful. Very nice and patient waiters and excellent service, but not likely to revisit.

A place right by the window - incredible drinks, a delicious burger (I know, not a fancy order but it was amazing) and incredible wait staff. Loved the experience!

We opened catalyst on the very first day they opened after the shutdown. They were GREAT to us. When we go again I'll ask to sit indoor as it is lovely near the fireplace

The waitress was excellent. Personable, attentive, and knowledgeable about the menu.

It was a very nice place and the food was so delicious!

Delicious food and fantastic service. They have an upgraded ventilation system and some outdoor heaters too.

Everything was wonderful. This was dinner with a friend. Neither of us had been to Catalyst before. The service was professional, great ambience, good social distancing in the dining room. Lovely variety in the menu. Both of us will be back. It was a terrific evening.

Good food and service

Excellent job with outdoor seating for lunch. Food was excellent

We sat outside, 2 tables of 4 - very accommodating. Staff was great and food was delicious. They even validate parking :) Definitely will go back and recommend.

Love this placed and missed it when it was closed! Really hope they are able to survive COVID!!!

Always outstanding. The loungey outdoor setting is artfully done, and the food lovingly executed. 👍🏼👍🏼👍🏼

A lovely patio with trees and blue sky to enjoy delicious food in these crazy pandemic times. I highly recommend

Our lunch tacos were great1 Excellent fries as well. Drinks were a bit pricey but tasty; the only disappointment was a watermelon "salad" for $12 that was 8 small squares (less than 1 inch by 1 inch) of watermelon - very nicely garnished and dressed but SERIOUSLY???
It in no way was a salad, possibly an "amuse bouche" ... should have been a $5 charge at most -

Based on the price of this dinner item, I would probably NOT try the restaurant for dinner - there is no way that was a first course for one person, never mind a shareable plate for a table.
Service was great; safety standards were well maintained.

I am glad the Catalyst is back to business even under these dire circumstances. The service and the food was great. We sat outside under the trees. Lovely.

Great outdoor seating with lots of distancing. The food and service was great.

Fantastic food, excellent menu, great service. Can’t wiSt to go back. And the wine list was outstanding.

Amazing culinary experience as usual! Nothing short of perfection. Catalyst is gem of Cambridge and New England.
