All the other positive reviews got it right. Here's my tip for getting a seat. When you get there, look for a line on the sidewalk. If there is one, just get in the back of the line. If you go inside, they'll just send you out there. As people have said, the line does move quickly and they will skip spots in the line to fill open seats. If you're a single person you might get lucky and get in right away even if there is a line!
