also depending on the dates your out there, slims or bottom of the hill, or the parkside could have some good bands playing.
bottom of the hill and the parkside are kinda close to slims, but i would drive there , but you can walk to slims (11th and harrison) from most places. plus Butter is right across the street and the DNA lounge, those are worth checking out once.
also my personal favorite bar out there is the cozy car. they are set up with cans of pabst for cheap, the bar is modeled to look like a shaggin waggin and the booths are like the inside of an old school shaggin wagon. they also splice porn into cartoons on the Tvs if you pay attention. pretty cool.
also, there are 2 cool tiki bars i like, ones in north beach, and ones inside the fairmont, i think. scorpion bowls are fun thing to do. the one in north beach is cheaper and you get way bigger bowls.
