Between the rumblings of L trains passing nearby and the vibrations from bands playing downstairs, this fourth-floor South Loop rooftop isn’t for the faint-hearted. But what it lacks in refinement, Reggies Trainwreck Rooftop Deck — actual name — more than makes up for in unpretentious charm. Grab a spot at the bar, where friendly bartenders can walk you through the menu of no-frills drinks — a Vegas Bomb, perhaps? — at prices below your usual rooftop hang. Or grab some friends and order fried pickles, chicken wings, and Garbage Fries to share at one of the metal picnic tables. The pool table and Pop-A-Shot are free, and should you work up a sweat, there’s an outdoor pull-string shower to cool you off. 2105 S. State St. reggieslive.com
