Well, if people are grossed out by the Salsaburger, this place makes others. Here's a few others I've had over the last 3-4 months (I go about once a week). I'd like to point out that the cokes are Mexican, with real sugar.
This one was called Tom Selleck's Mustache, and it had a Roasted Garlic Jalepeno Catsup.
This one was called the "Colonel Mustard", and had a Stone Ground Mustard sauce.
This one was called the "Ty Cobb", and had a Georgia Peach BBQ Sauce on it.
