D’Sens (Dusit Thani, Rama 4 Rd., 02-200-9000) is now having a fancy happy hour deal in August, called Sunset at D’Sens. Every Fri from 6-9pm, there will be a free-flow offering of four of their signature cocktails (as well as the standards) for B850 net per person (which happens to be the price of a weekday set lunch as well). For B350 (not net) more, you get a few tapas as well. The bar is usually pretty quiet but the views on Lumpini Park Park are unique.
