First-highly suggest you check the wait list, and join before going during peak times. We were lucky to grab a table at the bar, and bypassed the hour+ wait.
My daughter and niece proclaimed the burgers to be the "best they've ever had", and judging by the lack of leftovers-they were correct!
I've heard others complain about poor and/or slow service--we had the direct opposite. I highly recommend you try to get "Jillian" as your server! She was prompt, and super friendly! The best!
