6 hours in Columbus Ohio

I have 6 hours in #Columbus #Ohio. What should I do?
  1. Go to the original Wendy's?
  2. COSI!
    It's a fantastic science museum. Kid-oriented, but still great.

  3. Katalina's has great breakfast/brunch food. The Franklin Conservatory is gorgeous if plants and Chihuly glass are your thing. Lots of fun things to see on OSU's campus and down high street, esp if you're a Buckeye fan. Tommy's pizza is also very good.
