The burgers, beer and fries are very, very good. Unfortunately, the service sucks.
It's hit or miss anytime you go. This is a very popular restaurant. They've been open long enough to get their sh*t together. They just don't seem to be able to serve customers consistently. Sometimes it is fine, other visits can be a total disaster. You can experience MIA waiters, an abandoned check-in stand and delayed or confused orders.
The poor service really puts a damper on your dining experience and will make you forget how fun the food is. You have to be strategic about your dining times so you don't get lost in the chaos.
