I haven't been to SF in ages (I know-I should come back) so I was unable to help when my wife's Aunt asked me this question-
Her 20-something grandson and wife live in SF and both love lobster. She wants to get them a gift certificate for a restaurant that serves terrific lobster. So I need a place that always serves it. And I'm thinking she'd like something a little above a fish-shack kind of place. They travel a lot and could deal with any level restaurant.
Any suggestions would be most appreciated.
