Mad Men may be over, but '60s nostalgia lives on. The Freeze is a vintage time warp, and while there aren’t nearly as many locations of the fast food restaurant as once dotted Chicago (there were dozens), you can still find one in Logan Square. In the summer, there’s a walk-up window and picnic table seating. The savory items, like corn dogs and burgers, aren’t much to talk about, outside of living John Cougar fantasties of suckin' on chili dogs. The ice cream menu, with milkshakes, sundaes and soft serve, is the main draw.
