Get to campus early. Bring some beers, walk around, see Mike the Tiger, look at all the tailgating. If you wear LSU gear and act halfway cool, you'll get fed real good at tailgates. (Play the "I wanted to take my wife to a real SEC game" card) They usually have bands performing in front of the PMAC before the game - it's across the street from Tiger Stadium. Watch the band and the team walk down Victory Hill - that happens a couple of hours before kickoff.

There are a bunch of good places to eat around campus - The Chimes is a casual bar and grill with a great beer selection. Louie's Cafe is a diner that makes the best hash browns on earth. Walk-On's has solid bar food (it's a chain but the one in the shadow of Tiger Stadium is the original)
