Tipp City has at least a couple of decent places I can vouch for: Coldwater Cafe, and Hickory River Smokehouse (BBQ). The pulled pork @ Hickory River is excellent.
I think I’m too new here to post links, but they both come up easily on Google.
Troy, OH is close by. La Piazza (Italian) is pretty good there. If you can make it to Dayton (half hour drive), then options open up quite a bit. My top picks there are Rue Dumaine (French Bistro), and The Pine Club (old school steakhouse).
