Unfathomably disgusting burgers on both occasions I gave them a try.
I don't understand what all the hype is about. The first time I went, I got a burger. I don't recall which type. It tasted like whatever charred material was stuck to the grill. I couldn't take more than two bites. The burger literally tasted like whatever was burned onto the underside of a grill. Soot and a not-quite-right meaty flavor.
Since I had a gift card, I decided to give them one more try, because hey, everyone's entitled to a bad day once in a while. I regret this decision. I got a burger with some sort of basil cream cheese on it. Again, the burger tasted like the burnt underside of a grill. Absolutely, positively, the most disgusting burger I have ever had. The toppings were fine; the burger was crap. I had a side of fries. They probably would've been good if they weren't cold. A little overseasoned if anything.
A burger almost anywhere else is guaranteed to be better.
