I've visited this location on two occasions, approximately 6 weeks apart.
The food is awesome - well worth the wait.
Get here EARLY as the lines get crazy, especially around 10am - noon; expect to wait about 50 minutes in line. For best seating times, go closer to when the restaurant opens.
Tables and area are tightly packed. The atmosphere is really loud once the hustle and bustle starts.
Not that I typically encourage this, but take a trip to the bathroom AND bring your camera: you'll be in for a really cool surprise! Wash your hands after, though, you filthy mcnasties!
