We were there in Oct for a baseball playoff game and it was really crowded. We shared a table in the bar with a nice couple from England. It was a great way to meet other people. I would imagine Superbowl Sunday would be very crowded, but fun!
We will be there for the last 2 games (maybe) of the World Series and we are hoping to goes to game 6 & 7 so we can watch it at ESPN. It is a fun place if there is a big game on.
