Being from Columbus and simply to make a contribution to the board - Columbus certainly isn't Chicago in terms of the culinary scene, but we do have some gems.

For the vegans, Dragonfly is excellent and Pattycake Bakery is amongst the best baked goods (vegan or not) that I've ever tasted - it bests Bleeding Heart for certain, IMO. Kihachi is home to some wonderful authentic Japanese food (not just "sushi.") Alana's is doing Farm-to-table quite nicely, with a French Twist.

There are others - http://uhockey.blogspot.com/search/label/Columbus
