My husband and I checked out Range on a recent weekend trip and very much enjoyed it. It was recently awarded one Michelin star, and is located the very young and hip Mission District. While it's not an all-out luxury experience as is the FL and some other restaurants mentioned here, if you're looking for a more casual fine dining experience in SF, it can't be beat. We each had a starter and an entree, shared a dessert, and enjoyed a reasonably priced wine, and the bill after tax and before tip was about $130 IIRC.
