Saw mention of SkyBar, and it's not bad if you don't mind rubbing elbows with primarily fraternity/sorority types (and yeah, the sorority girls are hot...but then, almost all of the women in Auburn are hot, just like most every other SEC school). The better place to drink is the War Eagle Supper Club...due to archaic Alabama state laws, alcohol can't be sold on Sunday until after noon (presumably because you're supposed to go to church before getting your drink on). However, the Supper Club gets around that by being a private club (you have to buy a membership, for a dollar or two, before you can go in, though if you keep up with the card you won't have to do so again) and thus can go much longer into Sunday morning. Good music there, too. If you've ever seen the Velcro Pygmies, that's the spot they usually play in Auburn.

As for eating, Niffer's has some of the best burgers you'll ever find. I LOVE the mushroom-swiss burger, and the corn nuggets are a treat.

Momma Goldberg's is a great sandwich place that has expanded throughout the southeast, but started in Auburn in the 70s (the first shop is still there, corner of Donahue and Magnolia). If you go there, the Momma's Love is THE classic serving, and the nachos are awesome (pepper jack cheese steam melted onto Doritos).

We also recently got a Five Guys Burgers and Fries downtown on College Street, and while not an Auburn original, that place is freakin awesome. Burgers aren't quite on the level of Niffer's, IMO, but they're as close as I've had, and the fries are also outstanding.
