Mmm, how 'bout those buns? Now with three Chicago locations, Wow Bao specializes in bao, savory steamed Chinese buns filled wtih Kung Pao chicken, BBQ pork, green vegetables and more, making it the country's first "bao shop." Also offering broths, salads and specialty Asian-influenced sodas, frappes and teas, all for less than a fiver. In fact, you can get two bao and a pad thai salad for a healthy $4.69.

Try the house ginger ale, brewed fresh from real ginger root and served with a twist of lime; it's much spicier than Canada Dry.

Average cost: <$10
