Forever Yogurt (CLOSED)

This pay-by-the-ounce fro-yo concept has plans for Chicago domination. Even more ambitious is the CTA-inspired concept behind its late-night Lakeview location, where the selection of pull-your-own frozen yogurts (in trendy flavors like red velvet and cake batter) is housed in a faux Red Line car, and the wall boasts a mural of the transit map. Grab as much of as many flavors as you want, then head to the topping bar, where everything from fresh fruit to candy pieces awaits. One reminder: the fro-yo may be healthy, but this experience still culminates with a weigh-in.
