I figured since DC is such a hodge-podge of people from everywhere, someone might be able to make a recommendation for dinner in San Francisco on Monday night. I'm on work travel and I'm staying at Union Square. I'll probably be dining alone and if possible would prefer something walking distance. I like many different kinds of restaurant, new american, thai, mexican, italian, etc. I've eaten all over DC. I appreciate good food, and wouldn't mind going somewhere that has different food than DC. Nothing crazy expensive, but I'd probably be willing to pay $50 for dinner, not including tax/tip (and I'm not drinking alcohol). Any recommendations would be appreciated!
