Burgers are good but the service is SO SLOW and the lines are always so long. Food is inconsistent also. Every visit they are out of something from their menu. Last visit they were out of avocado. :( And that's one of the main reasons I choose there to get a burger.
To me, at a minimum, a restaurant should have all of their menu items in stock at all times. I won't go back, there are plenty of other burger places that also provide good customer service.
