I know there are a million threads for what to eat in SF, but I thought I might have better luck by being specific. I'll be in town for two days (midweek) in March, I'm staying at the Chancellor in Union Square and won't have a car. I'm from LA, so I'd rather avoid Mexican food and eat what the locals do best. I'm thinking one splurge meal and moderately priced the rest of the time. I'm open to all cuisines, but not a particular fan of shellfish.
Also, what do you guys think of these places specifically:
Blue Bottle vs. Philz for coffee?
Delfina vs. Una vs. Tony's vs. Caffe BaoNecci for pizza?
Is Sam Wo a tourist trap, or are there good cheap eats to be had there?
Are Roli Roti or Chairman Bao worth a look if we run across them?
Any specific recs for a bakery/cafe at breakfast?
Thanks so much for any help! Hounds always know the best places :)
