Firefly was my introduction to truly great California cooking: subtly perfect flavors, incredibly fresh local ingredients, and effortless fusion of cuisines from all over the world. We've had everything from sushi to old-fashioned meatloaf here, and the kitchen never falters. The tasty lentil spread that comes with the bread (in lieu of butter) is a delectable touch, and the shrimp & scallop potstickers alone are worth the trip. Overall the experience is food as an art form - but without the fancy trappings of a more formal restaurant. The atmosphere is relaxed and homey, like having dinner at a friend's house. My only nitpick would be the host/hostess, who can be a little snooty if you don't look like a Noe Valley type - I made my first visit as a frumpy college student, and we waited 20 minutes despite having a reservation.
