Couple quick tips - don't park too close to the stadium, if you're willing to walk a few blocks you'll get much cheaper parking a bit farther out. If you like pizza, MOTO pizza on the 300 level is *chef's kiss* and you have to get garlic fries.
Spent some time at Hatback Bar & Grille which had a good vibe, but can't remember all the other places we tried. You'll have a blast.
