I am going up to San Francisco this weekend with a group of about 7 to 10 art students and instructors to see the current exhibition at SF MOMA. We will be meeting for dinner on Saturday night. Does anybody have recomendations for dining in the area? We are looking for a low-key place that has a bit of atmosphere but isn't too stuffy or expensive. But for the instructor's sake, it shouldn't be a hole in the wall (we've had enough cafeteria and fast food!). Any suggestions are greatly appreciated!
