Slip into a flapper dress or twirl a handlebar 'stache for this fourth annual, Prohibition-themed bash at Webster Hall. Guests can revel across the four-floor, 40,000-square-foot space, which includes a pop-up whiskey lounge doling out 90 types of hooch that hits both domestic stalwarts (Knob Creek, Jack Daniels) and beyond (Knappogue Castle, Tamdhu). The beer front is similarly international, with Texan Shiner Bock poured alongside French Kronenbourg 1664 Blanc and Swedish Rekorderlig cider. Your ticket is good for a commemorative glass and three hours of limitless sampling. (Pony up an extra Hamilton to get in one hour early.) Live entertainment comes courtesy trapeze artist Autumn Burnette, Queen Esther's Quartet and jazz-age dance band Michael Arenella & His Dreamland Orchestra.
