Hanging out at UnderTow is exactly like sailing the seas in a 19th-century ship's hold — if your boatmates were thirsty hipsters instead of weathered seamen. From the moment you descend the staircase in the middle of Arcadia's Sip Coffee & Beer, you're in a drinking experience unlike anything else in metro Phoenix. The tiny underground space is adorned with faux portholes and barrels, tiki carvings and lanterns, to set the mood. Then come the drinks. UnderTow dropped a new menu in mid-September. Like the previous two iterations, it's divided into UnderTow originals and tiki classics, and most drinks on both sides of the menu are new to the bar's lineup. We like the fruity, potent Signal Fire, made with tequila, rums from three islands, orange curaçao, mango, habanero, orange, pineapple, and lime. Note that the bar only seats a couple of dozen people, which makes for a friendly atmosphere among the guests, but also makes a reservation (especially on the weekends) virtually mandatory.
