Busy Sunrise Boulevard might seem an unlikely place to find Serenity, but that's part of the charm of this cozy day spa. Open in the evenings, the spa makes it easy to find time for a little peace. It even issues an order for bliss: "No cell phones," declares a sign at the door. The walls are the color of daffodils; the scent of Aveda oils wafts through the air. Sink into a comfy chair tucked into a cubby space while the affable, black-clad staff pampers your feet. Try not to think about your to-do list, because too soon your perfected feet will be back in action. This moment will be a memory. In fact maybe Serenity should put up another sign: "Relax. No Multitasking."
