Hi ladies! I live in the DC area but will be in San Francisco for a conference next week. I've spent very little time there in the past (all for business, and I got dragged to crap tourist traps by coworkers), but I know it's a wonderful place. I'll be based in Union Square and won't have a car, so some advice on how to get around, good places to eat, and a good place to get a pedicure would be greatly appreciated! TIA!!
