Restaurants in Louisville?

Depends on how nice and budget but here are a few different styles: Lillys is terrific as noted above in a previous post.
Proof on Main
610 Magnolia
Jack Frys
Mozz - Italian
Equus
Seviche - latin inspired
Basa - Modern Vietnamese
Coals Artisan Pizza - Coal Fired Pizza Oven
Lynns Paradise Cafe - Breakfast

I haven't been there in several years, but my friend Kathy Cary has a lovely bistro called "Lilly's," where I found the food really delicious. ;)
