Completely over rated. I've been there about 7 or 8 times and never had a fantastic burger. It's not bad.......it's just not great. Maybe it's because my childhood was never a memorial day BBQ kind of childhood, that I think thin burgers are pretty meh. They just never have that juicy medium rare middle that I long for. Lines are too long during peak hours and you wind up waiting just as long on off peak hours. It's hot. The chairs suck. The fact that the bathrooms are outside for some reason grosses me out.
It's not that I will never eat there. I just won't go out of my way to eat there.
