Charlie Brown's is a very unique restaurant, far from the big chains and francises that you're familiar with. The restaurant is small and very casual. While dining there, it feels as though you're in a home. Bookshelves filled with various volumes give an extra cozy touch and this is a fabulous place for a date.
In regard to food, it is moderately priced and quite tasty. It's nothing to write home about, just standard American/grill type food, but the atmosphere makes Charlie Brown's worth a visit.
