I moved away from Columbus about five years ago, and I know that a lot has changed on campus since then.  I have only been able to make it back intermittently since then for a game here and there.  My wife will be visiting campus for the first time since she was in high school and took a college visit.  She does have some food allergies, so did not know if anyone knew of any places that have a lot of dairy-free options either on campus or around the downtown area?  Any recommendations would be extremely helpful!
