The service was sub par when I went. By the time I could eat my burger (they forgot an ingredient), the rest of my burger was cold!
Nonetheless, the burger tasted great when I got home and ate it.
You are able to customize your own burger via a small clipboard with options you check off. It's about $10 with a drink for a decent sized burger.
They accommodated our group of 12 quite well considering that the place isn't that big, But, customer service was affected... tremendously.
I would probably go back because I am interested in trying out the other creations, but I haven't. I am just not that big of a fan of burgers in general.
