I have a school graduation coming up, and a few friends and I would like to go out to dinner afterwards with our families. There will probably be 12-20 people total. We're looking for a place that is nice but not too expensive - maybe around $20 a dish. Also, one friend and her family are all vegetarians, so the menu has to be vegetarian friendly. And obviously the place needs to be able to accomodate large groups. Any suggestions? Thanks!
