Their online menu is really nice if you are gluten free (it is easy to follow). They also are cool about wrapping your burger in lettuce and don't upcharge you for asking for no bun. Wow.
Anyways, the burgers are HUGE and to die for. Even if you can eat a bun, you should still get it without one so you can finish the burger.
I must admit. I went to Wendy's today and realized I like their burgers just as much and they are much cheaper.
