Went to Brassaii last night with a group of friends for a welcome-home party for one of the girls. We walked in past their outdoor areas that looked fantastic. I loved that they had an outdoor fireplace for drinks. However, we were there for dinner. It was a bit early to eat on a Saturday (our reservations were for 7pm) and the place was a bit quiet. From start to finish, the service was extremely attentive and friendly without being pushy.
The building itself is beautiful and it is divided into a spot for drinks at the front and the restaurant in the back. The ceilings are high and the walls are painted brick, giving it a really airy and clean feeling. However, I felt that the lack of soft furnishings (other than some banquette seating) made for an overly noisy atmosphere.
The food was good -- I had the gnocchi which had lamb chunks and mint in a tomato sauce -- but it didn't blow me away. The dessert I had, however, was fantastic (the parfait) and they had some nice touches, such as a cocktail cart that a bartender brought around to each table.
All in all, it's a good spot to go with a group of friends -- in fact, all of the tables there seemed to be large group reservations -- with a menu that will please everyone.
