I got the bacon cheeseburger with a gluten free bun. The bun was super dry and the top of the bun was rock solid. The burger was good but since the bun was so dry it needed some condiments on it, as there were none. And also the pickle that was on top of it looked like it was sitting out for a while..as it was really dehydrated.
And you know how most places at least give you a couple free sides before you upgrade? You know, like a choice of salad or fries? Naw, you only get fries, which in my case wasn't an option since they weren't gluten free. So on top of having to pay for a nasty, hard, dry bun that was a $4 add on gluten free bun, I had to pay an extra $1.50 to get a mixed green salad. That was the best part of my meal. The balsamic dressing that came on it was really good.
So overall, I wouldn't recommend getting a gluten free bacon cheeseburger. I'd stick with getting a salad at this place since you have to pay for all your sides which makes your meal really expensive.
