I was lucky enough to go to the new Cowboys Stadium two years ago, and the pictures that you see on television and the stories you hear about it simply do not do it justice. It barely mattered that the Bills were absolutely embarrassed on the field. The atmosphere outside of the stadium as far as tailgating leaves a bit to be desired, nobody outside of Green Bay and Kansas City tailgates like Buffalo, but inside the walls it is a mecca. It's the cleanest public place I've ever been in, not just cleanest stadium. We did not wait in a line all day for food, beverage or piss break. The only thing that bothered me about the concessions was that Miller has all the marketing rights, so all that was being sold was Genuine Draft and Miller Lite, which I hate, but the food selection was outstanding. The architecture of the stadium is incredible, and many of us stood there in awe for a solid 10 minutes when we first walked in admiring it. Also, the Dallas fans were actually extremely respectful and courteous to everyone in our group. Even as we were getting the tar beat out of us. Lastly, the cheerleaders, including Nelson's ex, are second to none.
One note I would add is that the stadium is in Fort Worth, and there isn't much to that area. If you do go there for a game, stay right in the city of Dallas and make the 40 minute drive to the stadium. I was very impressed with the food and bar scene of Dallas, and the people were great. I would recommend making the trip for a game to anyone that asks, and look forward to doing it again myself in the future.
