I had always avoided Sideline's because friends had told me that the service was terrible. But during the World Cup, friends and I decided to give it a shot. I was terribly disappointed.
To start, Sideline's COULD be a fantastic place. There are more TVs than almost any other sports bar in town, and they've constructed really nice seating along the walls. What kills Sideline's is that it's woefully understaffed, so any time there's a rush of people, you can't get served. As in waiting 45 minutes just to see a server.
Once they add more staff, I'd be happy to change my review.
