While the menu appears to have several options, they actually don't. The options are grilled, burgers (also grilled), or salads (some with grilled toppings). They cannot guarantee no cross contamination occurs on the grill, so that rules out everything grilled. Only one salad dressing is GF, so what's the point of getting a salad? I will give our waitress credit for having the knowledge to inform me of all of this.
