The brothers Wahlberg (yes, Mark, Donnie and Paul) expand their fast-casual burger empire to Chicago with a 5,000-square-foot restaurant in River North. The aptly named Wahlburgers serves speciality patties—like the O.F.D. with Swiss cheese, bacon, mushrooms and tomato jam—as well as bowls, salads, sandwiches and floats. Little ones will appreciate the robust kids menu, with options like grilled cheese, chicken tenders, mac 'n' cheese and an ice cream cup. Watch reruns of Wahlburgers, the A&E show that documents the brothers' foray into the food industry, before hitting up this River North joint for a burger and fries.
