I've visited Brixx twice since they opened. The first time was last week for lunch with a friend; the second time was tonight for dinner with my wife.
I have to say, that overall the service was very good and the food was something I would come back for. For my lunch visit I had the roasted chicken club sandwich on focaccia. For my dinner visit I had a pizza that was half Bronx Bomber and half Chicken Florentine.
The only reason I'm giving Brixx four stars instead of five is because the noise level this evening was absolutely unbearable. I had to yell to have a conversation with my wife, and more than once we could clearly hear the servers at other tables because they were having to yell at people at the tables. I understand that restaurants can be loud at times, but the fact that extreme noise seems to be the norm here means that I won't be coming back for dinner.
If you want to enjoy their food (which I would recommend) then do your best to come for a mid-week lunch. If you're looking for a nice place for dinner, I would skip it unless you want to feel like you're having dinner at a rock concert.
