We have tried several Brazilian restaurants in Cambridge and Boston, and I can assure you that Muqueca is the best.
The restaurant itself is not too big, very cosy. We had a dinner there once with my fiance and then I decided to make a surprise dinner for him for his birthday. I was amazed how well Fatima, the manager, and her colleagues managed our big company (22 persons!). We were even offered complimentary starters. The food was amazing: I ordered shrimp muqueca, it was delicious! And at the end of our dinner, the staff brought the cake that I got delivered in advance, and they sang a song, so it was really nice of them to contribute into the birthday party mood.
By the way, one of our friends forgot his bag with a laptop and the manager notified me immediately on the phone.
To sum up, I definitely recommend Muqueca for romantic dinner, family dinner or any party, it is a lovely place with lovely people.
