Meeting my old college roommate in Princeton for lunch. She's not much of a foodie, but I am known to be a bit finicky about the food. It doesn't have to be high end...just good quality ingredients that are well prepared. She's pretty frugal so not sure an expensive meal would be her thing. So I guess I'm looking for suggestions of somewhere to go that isn't overly expensive, has good quality/interesting food, and where they wouldn't mind if we sit and chat for awhile. Ethnic suggestions would be welcome as well.
