ESPN does not take Priority Seatings. The smoking/bar area is 1st come 1st served, watch out during football - there are vultures!!! They will stand over you and wait for you to finish. I almost got into a fight with a woman the last time I was there! The non-smoking section, you have to wait in a line, like a club. You can't leave your name or get a pager like other restaurants.
It depends if you're going during a sporting event or not if you will hit a crowd, also depends on what time of day.
