There are so many detailed reviews here that my 2 cents is probably only worth 1 - if that.
Loved: as I was reading the menu board, grill guy says "is it gunna be beef?" so that he could get my burger started, regardless of my toppings.
Loved: service at the cash, super friendly & genuine. They take your name and when they called out mine, it was more of a familiar "Chris, dinner is ready!" rather than a monotone "next..."
Loved: the "plate", a metal rectangular thing, made the burger look that much better.
Loved: the burger. Really, really did. It was messy, about 4 napkins messy. Awesome. I could taste each and every ingredient. So good.
Loved: the little window seat. I would go back for that seat alone.
Next time: I hear the Onion Rings are killer.
