You can't throw a rock without hitting a great restaurant in the Mission. NightOwl lists some nice ones - here are some others: Beretta (Italian/American - great cocktails), Schmidt's (German), Locanda (Italian), Rhea's Deli on Valencia (great sandwiches - get one and head to Dolores Park!), Saison (French), Osha (Thai). You can't go wrong with any of these and the above. I'd hit up yelp and just see what looks yummy to you. Happy eating!
