I consider this place my hidden lunch gem in Phoenix. I work downtown and I often don't want to spend half of my lunch hour waiting for a table at the normal places. I've never ever had to wait at SunUp. The staff is always friendly and accomodating - never had one with a bad attitude. For my money, I prefer to sit in the brewery area and enjoy the quiet it provides. Lunch here is always quick, delicious and cheap for what you get.
Would definitely suggest the Camelback Club, Burgers and Pretzel Bites!
