My husband and I will be driving from Pittsburgh to Columbus en route to Richwood, and picking up his sister at the airport on the way. Because of the long drive and unpredictability of Delta flights being on time, the timing might be tricky. I'm therefore in search of a cafe/restaurant fairly close to the airport where we could potentially kill some time and grab a bite - I'm vegetarian, but husband isn't. A quick Google map search turned up a Starbucks in Gahanna, but I'm hoping we can do better than that. This will be mid/late afternoon, so breakfast/lunch-only places are out. Grateful for any suggestions, thank you in advance.
