I would suggest "The Old Tavern" in Unionville, Ohio. It is an historic old restaurant. In fact the first job I ever had was washing dishes there.
You can get there from the RT534 exit on I90. Their phone number is 440-428-2091. I am pretty sure they serve on Thanksgiving day. I am assuming you are traveling down I90. If you are driving I-80, or I-76 let me know, I have a friend who knows that cooridor well.
If you are going down I90 and need a safe sleepover stop, I have place here with a 30 amp outlet, just 2 miles off of the I90-RT44 exit.
