Top 4 restaurants in Knoxville:
1.)Bistro by the Tracks (or By the Tracks Bistro, however you want to call it) and I think it was better before it moved next to TGI Fridays and Aubreys dude took it over.
2.) Nama - duh, eaten sushi all over the world, and just can't get enough of this delightful fusion sushi.
3.) Pasta Trio - rustic, simplistic italian, BYOW gem. fresh pasta, and if u don't find anything on the menu 9 times out of 10 the cook will make u whatever u want.
EDIT (forgot 4)
4.) Northshore Brasserie - very simple french...terrible location imo, but outstanding seasonal menus.
really, as far as anywhere else...bleh. Ruths Chris is ok i guess due in part that we don't have much else to choose from when considering quality dining.
