Grab your parka and get to the Envoy Hotel to park yourself in one of the Lookout Bar’s six rooftop igloos. Every Wednesday through Saturday from 4:00-10:00pm, master mixologist Brian McDougall is crafting specialty cocktails to keep you warm (there are fleece blankets, too) as you chill out in the heated igloos, which are available on a first come first served basis. Each orb can comfortably seat 8-10 people and all you have to do when you’re ready for a drink is press a button to illuminate your igloo, which notifies a cocktail server of your request. Visit their website for more details, and call 617.338.3030 with questions.
