Okay, now we're talking! This is my kind of food tour! And even though the caloric intake is way more than what you'll be burning off walking to each new sweet tooth hot spot, I can trick myself into having that extra triple glazed double chocolate donut because I'm "burning it off." Founder of the Underground Donut Tour, Jeff Woelker might be the biggest donut enthusiast I've ever heard of, and that's saying a lot considering Guy Fieri and Adam Richmond of Man vs Food are both HUGE sweets guys. If you're in Chicago for a weekend, check this tour out! Some of the best donuts the city has to offer plus you might learn a few things about donuts on the way! Just be sure to bring your walking shoes and remember, calories don't count against you if you're having fun.
