Tudor's Biscuit World is legit! The "Thundering Herd" biscuit is the diabeetus but is delicious.
The Hall of Fame has pretty good food as well. Standard sports bar food, lots of Herd memorabilia, has a local feel to it.
Pullman Square is sort of a smaller version of Newport on the Levee in Newport/Cincinnati. It's not going to blow you away but it's a nice place to walk around & eat. It's on 3rd Avenue, down the street from the Stadium a mile or two, right in downtown. Plus there's a big hotel (can't remember what it's called, it's a Marriot or something) immediately beside.
I can't believe you left The Pub off of there! The Pubwich is unique and delicious. Stewart's Hotdogs is also classic.
Music lovers should hit up "Now Hear This!", a mom & pop music store. Tons of CDs, DVDs, vinyl, shirts. Music geeks can spend hours there. It's on 4th Avenue.
I ended up in the area b/c of CSX closing down its Louisville shop and my father's job being moved to Huntington as a result; if you want to see where everyone ended up, the CSX shop is on 5th Avenue. Lots of Louisville natives ended up in the area b/c of CSX.
