Cincinnati unique places/dining?

Hello, I live in Cincinnati. I actually just moved here this past August and I am having a lot of family and friends visit this year. I need some help in showing them around. But I don't really want the usual places, Aquarium, Zoo, King's Island, etc. I'm looking for the more obscure and interesting places to see. Also some hole-in-the-wall, one-of-a-kind restaurants that are worth going to. Unique places only please. Any locals know of anything great? Thank you for your help.

Take them down to Riverside Drive in Covington to take a walk along the river front with a great photo op of Cincinnati. Not to mention the wild life playing on the river, I have seen beaver playing on the river bank there along with the locals fishing. Take a loaf of old bread with you and watch the ducks go wild for a piece. Then there is Traders World Flea Market open on the weekends a little north of Cincinnati up Interstate 75. Or if you are truly in the flea market spirit you can go to the Kellog Ave. flea market where they still sell junk along with an occasional treasure. Then if they are here during the last Friday of the month you can take them to the Pendelton Art Center for Final Friday which is their monthly sale on the final Friday evening of ever month. The Krohn Conservatory in Eden Park is a really nice place and often over looked by locals. Of course there is always Jungle Jim's up in Fairfield ,
the most unusual grocery store in the world. You can let them pick their dinner while it is swimming around in the one of their live fish tanks. The shops in Northside and Lower Clifton always offer the unexpected to bazaar.The Findlay Market is always nice early in the morning for a unique food shopping experience.

Welcome!
Try Biagio's on Ludlow in the Gaslight District.
It's a little Italian joint where Biagio, bless his fat little heart, cooks in the dining room. Very nice, but home-y and reasonably priced.
There's a little-known neon and other type sign museum that's way cool. signmuseum.com

Take them to Krohn conservatory to look around. This would be especially cool during their butterfly show that is normally in June/July.

Grab some Skyline Chili and some Graeters icecream and head to Ault Park for a true Cincy picnic!

Green Papaya is one of my favorites. The atmosphere is wonderful and the sushi and thai is some of the best in the city!

OK- for a restaurant, I have a great Cincinnati secret for you- its called Vincenzo's, and its on Chester Road in the Evendale area, very close to Princeston High School. Its true, authentic Italian food, cooked by an Italian, and its some of the best you will ever have. We happened to start up a conversation with some other customers there one time, who had moved to the Midwest from New York City, where these people said that they had frequently gone into Little Italy and had wonderful Italian food. Since they moved to the Midwest, they had not been able to find anything that was even close. Someone had told them about Vincenzo's, and they had driven 3 hours to try the food and loved it. They came back every couple of months since it was the only good Italian the could find.
For non-food things, thats a bit more difficult, as I consider a lot of the things in the general area to be somewhat well known. Here are a few that I generally dont see suggested: Antique shopping in downtown Lebanon, Ohio, the Underground Freedom Center downtown, Union Terminal, if you are willing to drive 45 minutes north to Dayton there is the United States Air Force Museum (which is a really great museum), and lastly- Fort Ancient State Memorial, which is off of I71 to the North, where you can see some of the mounds that the ancient Native Americans built, and an associated museum. Depending on when your friends come, you could also potentially take them to a race at the Kentucky Speedway.
