My husband and I haven't eaten red meat for about 15 years, but we still love getting a veggie burger with lots of good toppings. The bigger the list of toppings (including cheese), the happier I am.
We love the Black Bean burger at Zodiac, the little veggie wimpies at Rocket to Venus and even (ever so occasionally) the Boca burgers at Johnny Rockets. Gertrude's does a nice black bean burger although the patty isn't homemade.
Any suggestions for other places?
