I'll be visiting in late April for four days with some college friends--there will be five of us. We've got Saturday night dinner plans (St. Vincent), we're planning to go to the Ferry Market at some point, and maybe take a taco stroll in the Mission on Saturday afternoon. I'm looking for suggestions for dinner or lunch options. Cheap is always great, but we can have a fancy meal or two. Also would love thoughts on whether Slanted Door would be a good choice. We're from all around the country, but none of us are from SF, so anything that's unique to SF would be fun for us. Thanks for any help.
Editing to add: I know this is a really common type of question on SF Chowhound. I've done some searching, and have come across some helpful threads, especially this one: http://chowhound.chow.com/topics/832505, but I'm hoping for some advice given that we'll have a bigger group. We're staying in the Nob Hill area, if that makes any difference.
