You might just cruise north on High St from campus to Clintonville. Lavash Cafe is a good Mediterranean option. A couple of other non-Mediterranean options are Local Cantina and Hot Chicken Takeover. I was also going to suggest Harvest Pizza, but it looks like it is temporarily closed. There are many other restaurants in Clintonville. If you keep going on north on High Street you get to Beechwold. Pat and Gracie’s is good. And if you keep going North you hit Old Worthington before you eventually hit 270. Old Worthington has Columbus staples like Old Bag of Nails, La Chatalaine, and Graeters.
All of these might be a little on the casual side. If you want higher end, you can always hit the Refectory.
