Brick by Brick is one of San Diego's best known places for concerts. Personally I've only been to see metal concerts there, but I believe they also have other types of music.
The places itself is a large rectangle with a bar in the middle, on one side of the bar there is the stage and concert area, standing room only. On the other side there is a lounge area and some pool tables. Normally this is the area where you can buy merchandise from the bands playing. And at the back there are some arcade machines with an area to go out smoking.
The bathrooms do not have signs, but the one on the left is for women, the one on the right for men. Just checked who comes out of them before you go in them. The service in the bar is fast and prices are average. Not very sure about the parking, since I've always been very lucky to find street parking very quickly.
Awesome place for concerts
