I don't live in So.SF, but I work and spend a lot of time there. Grand Ave. area can have a nice small-town feel and if you go to some of their restaurants multiple times the staff remember and appreciate you, and Buon Gusto is that type of place. Buon Gusto is a bustling old style Italian restaurant that is consistently good. Menu, albeit fairly standard, has solid veal and chicken dishes, several pastas including popular frutti di mare (sp?). Complimentary after-dinner shot of marsala is a nice touch. Meals are comforting and satisfying. Place is as elegant or casual as you want to make it. There are a lot of things I like about ""downtown"" SSF and Buon Gusto is one of them.
Pros: Good hot meals, Nice ambiance
