I travel to Cincinnati on occasion and have found a few good restaurants. DeFelice's - Creole / Cajun food. They have a live band some nights. Good food and service.
The Precinct - One of the older restaurants in the area. Great Steaks, white table cloth with a reasonable wine list. One of the best steaks I have had anywhere.
Montgomery Inn - Well known in the area. Famous for it's BBQ sauce and expecially the Ribs. If you enjoy ribs, don't miss this one.
