Wood's Pit BBQ is a favorite place; I go there for dinner (in my car) even in the winter! The Wandering Moose (it's actually in West Cornwall by the covered bridge; Cornwall Bridge is a few miles South on 7) is a good one too; I've been there many times for both breakfast and lunch. Neither place is going to be able to handle a really large group though. 10, 15, maybe even 20 at the outside but that's about it.
