Big D Burgers does fast food a little differently. Offering many healthy choices on the menu, Big D specializes in an American classic: the hamburger. Hamburgers are available in quarter-pound and whole pound options. Beer-battered onion rings and french fries make a tasty companion to the venerable hamburger. Alternatively, the Protein Plate, with two grilled chicken breasts on a bed of greens with grilled onions and mushrooms, is a satisfying option without all the calories. Fish and chips and grilled shrimp salad are also on the menu. The restaurant has plenty of seating to accommodate the lunch and dinner rushes. It has been serving Napa since 1983.
