Emily Szopa, writing for the Chicago Dining Examiner blog, surveys the Chicago hot dog scene in honor of National Hot Dog Month. She mentions, among others, Wiener’s Circle (“It’s loud, there’s no bathroom and you’ll probably get yelled at by the trash-talking staff, but they do have some of the best char-dogs around”) and Gene & Jude’s (“the memory of that first visit sticks with me almost 20 yrs later”), both listed on Roadfood.com. Special mention for Brasserie Jo, a French spot that's honoring hot dog month by serving dogs with mustard on a baguette for a buck, on Mondays only from 5-7 p.m.!
Beneath that hillock of fresh vegetables in the photo above is a Byron’s hot dog (from the Roadfood.com review).
