This friendly Loop lunch spot offers just a handful of items, but the streamlined menu allows the staff to focus on what they do best – Chicago-style favorites like hot dogs and chili. U.B. Dog offers a step up from your average hot dog shop, with high-quality Vienna beef ingredients for the neighborhood’s busy professionals. The paired down menu features steamed (not boiled) natural-casing hot dogs with all the fixings, including relish, mustard, onion, pickle and tomato (sourced from local vendors). Italian beef and chili play supporting roles, and just about everything on the menu is better with a side of hot fresh-cut fries.
