Roadtrip from NJ to TN, where do we eat? HELP!
I have been a long time lurker on SE, but have finally succumbed to making an account because I need your help!
On Wednesday morning I will be driving from NJ to Manchester, TN, and I have no idea where to eat on the way (there and back). Please help me out! I'm looking for some tasty places that aren't too out of the way.

My grandma's spaghetti and meatballs, or her 'pasta pizza'. The best pasta I can remember but can't recreate.
