Tim,
I haven't played The Farms or The Bridges, so I can't comment. I would hesitate to recommend a cart ball track like the Bridges over a walking course like SDCC. The Farms is meant to be greatly improved by the recent renovations and has the reputation for being a player's club.
Matt,
Although we don't hose down the streets with fire hoses at 4:00am like they do in King's Cross, I'm sure you could have a good time in the Gaslamp!
