The W XYZ Bar (Aloft Hotel, 35 Sukhumvit Soi 11, 02-207-7000) is launching a free-flow cocktail deal at B499 per person which includes their signature molecular and traditional cocktails and snack menu. The promotion runs through Apr 28, every Fri-Sat from 9pm-1am, which is actually when you want to drink. Cheers to that!
