Calling themselves the first full molecular cocktail bar in Bangkok, W XYZ Bar (1/F, Aloft Hotel, 35 Sukhumvit Soi 11, 02-207-7000) is rolling out its all-you-can-drink promotion again, which makes for good news regardless of the latest mixology trends. The prices are a little steeper than last time at B699 per person, but that gets you everything from their signature molecular cocktails and standard varieties to spirits and beers from 9pm-1am every Fri-Sat through Aug 31.
