I've had really good luck finding restaurants on tripadvisor:

Does anyone have any recommendations for a good place to have lunch in Luray, VA? We're doing a day trip this Saturday with some friends. We're looking for a moderately priced, casual spot for 4 adults, two of whom are vegetarian.
Thanks!
