I have a few suggestions:
**Definitely try to make it to German Village. It is such a cute area--hit the Book Loft--it is so fun and the only book shop I have ever been in that you can actually get lost in! A cute maze of books (literally). While you are in German Village, go to Schmidt's for lunch. Even if you just go for dessert after a sandwich at Katzinger's. Schmidt's is very famous for their German fare.
**Zoo is a great idea. Don't miss the Polar Bear exhibit. It is a very large zoo so you might consider some kind 2-day pass or combo pass with waterpark if you are going in the summer.
**I haven't been to the American Doll store yet--not sure when they are opening. They will not have a cafe'. FYI. There is a
Lego store there too.
**I second the idea of Graeter's or Jenny's (never been to Jenny's yet and I heard I am missing out... I'm a Graeter's die hard fan). You can get a tour at Graeter's ice cream factory (I think you can still do this).
**COSI is great too! A must stop.
**Shopping... I LOVE Easton but Polaris is a nice mall too!
**Amuesement Parks: I would hit Kings Island if you have time. The waterpark is INCLUDED in your park ticket. You can bring in a cooler into the waterpark as well if you want to have a picnic.
**There are also many other things to see... Franklin Park Conservatory, Thurber House,
tour OSU campus (beautiful old Campus) and you must see the Ohio Union. Here is a video of their flash mob they made not long after they opened, I think... pretty cool... especially if you are a Buckeye at heart!
