A conference (CVPR, the computer vision conference) brought me to Columbus, Ohio. The downtown area is quite nice and has a good assortment of interesting restaurants. I'm writing this review at Bareburger across from the convention center. It's a build-your-own-burger chain. They offer a wide range of ingredients that allow you to assemble pretty much any burger-like meal you want.
I had a turkey burger on lettuce with Amish bleu cheese and mustard. Very tasty with an appropriately meaty flavor provided by the bleu cheese. The service has been very friendly and attentive without being overbearing.
