at home i prefer turkey burgers, but at Rosie's All American in Hollywood Studios (formerly MGM) they have THE BEST veggie burger! Please don't be afraid to try it. That said, I don't think I've seen turkey burgers anywhere.....sorry.
The veggie burgers are Boca burgers which are okay but it can't beat a turkey cheese burger with lettuce, tomato, mayo, ketchup, pickles and relish thanks!
