Okay, what type of restaurant do you want? For nice restaurants Palomino is AMAZING! It is right above Tiffany, close to the Hilton. I know you said within walking distance, but Montgomery Inn is a Cincinnati tradition. It is right on the river, you would have to take a cab. There is also a Skyline Chili downtown which is another famous Cincinnati food. Also, Hathaway's in the mall downtown is a little cafe. It is not fancy or nice, but I just think it's so cute, I enjoy eating there.
