I just got back from the new Giants Stadium (New Meadowlands pfft!) and it's pretty impressive. The nicest thing was even though it was really loud, it wasn't ear-popping loud like the old stadium. I don't know why.
(when something is too loud I can literally feel it in my left ear, and it sounds like two concrete blocks scraping against each other).
And it smelled like sausage and peppers everywhere
Very nice concession stands and choice of food. It even has pro-shops fully enclosed with glass windows and doors like in a mall.
The funny thing though was that we couldn't find the escalators and used the stairs. Ouch! We weren't the only ones either; they're not well marked.
EDIT: I forgot to add the most important thing: During a commercial time out a black cat with white paws ran on to the field! I love cats so it was a good luck omen (a curse on the lady sitting next to me who said it was bad luck because it was black!). It ran freaked out on to the field from who-knows-where, the players watched it, and then it ran to the Giants sideline and behind a banner on a wall. Didn't see it after that.
