I'm in SF for a few days (arriving Monday, leaving Wednesday) and have time to go to three restaurants for dinner (M/T/W). I'd love to go to a great restaurant, that has vegetarian options. (I'm not that interested in a "vegetarian restaurant"). On my last trip I tried State Bird Provisions and Rich Table, which were fantastic. The trip before that I tried One Market, which was good, though SBP and RT I liked much better. Are there any comparable restaurants -- both in terms of quality and price -- to these places? Where I can walk in or get a reservation on short notice (hopefully being early in the week would help)?
