The Brus Room party is nice, food is great. And the "Bru" is short for Brudzinski. Try the triple threat sauce, uhhh my mouth is watering now... BBQ+Hot Wing+Garlic
It really depends on what you are looking for.
Unfortunately I have my tickets through work, and this is the game I have to give up.
If you just want to hang with other fans, I would recommend just walking around a bit. The lot surrounds the stadium, and this year they have brought in the food trucks. They circle the blue lot and you have a ton of food to try out. Just be friendly, say hello and most will respond.
The fanzone areas and pro shop is always cool to check out, even going every game we all tend to take a wok over there... They have a band, food and beer tents...
You will be wearing the proper colors to give you access to most tailgates tho. We do stick together
