Seafood restaurant at the corner of Steurt and Mission. A little expensive, but definitely worth it.
Wine list is over 1,000 bottles, fully stocked bar, pastry chef with awesome desserts.
Get the butter fish, the filet or pretty much any entree they have. I'd recommend the scallops or ravioli for appetizers and definitely the creme brulee for dessert.
It's very well designed, has an interesting ceiling, architecture, etc. Service is fantastic.
