A sensation in Miami Beach – part artful cocktail bar, part cheap sleeps. Has new home in Chicago’s upscale River North. Private or shared rooms, unfussy style with quirky art touches. Cafe Integral for morning jolt. But Broken Shaker is scenester spot, with snarky cocktails like the Banana Rum Manhattan and Cocoa Puff Old Fashioned, and a side of “street food” bites.
