In a couple of weeks, I will be visiting LA and San Francisco for the first time ever. I was wondering if you guys got any recommendations of places to visit. The usual stuff are easy to find via a couple of minutes of googling, quirky and cool are not (which I am more interested in). I am not after anything specific, it can be a little weirdish shop in some small street, some cranky underground bar (I listen mostly to hardrock/metal), or some place to eat. I am basically looking for something different. Any hints/guides/pointers are much appreciated. Thanks!
