we're visiting the bay area from boston, and we'd like to take our hosts out to a nice dinner somewhere in SF. we're a party of four, budget between $15-25 for entrees, any cuisine welcome. we'd prefer a relatively relaxed, cozy atmosphere (i didn't pack a suit).
for those of you who have visited boston, i'm looking for something similar to places like: grotto, ten tables, etc.
and to jumpstart the discussion, we've got a lead on a place called chapeau. thoughts?
