I'm sure some of these tailgaters will chime in as the game approaches, above is the parking lots map link.
You'll be close enough to walk, due South on Kirby Drive about ⅓ mile and you're right there.
Papadeaux's Seafood Kitchen and Pappasito's Cantina are both good seafood & Mexican restaurants nearby -- just South off 610 South Loop -- and both "safe" for crowd & food. A bit pricey, but they deliver. There's a Joe's Crab Shack right there, too.
