HENG Bar BKK is a bar on the third floor of ANNOP Eat & Drink in Bangkok's old town, serving cocktails, wine, and other drinks. It opens with a welcome drink and serves cocktails inspired by spicy Thai food, in a space decorated with southern Thai and Chinese elements. Going up to the third and fourth floors gives a rooftop view, and the bartender makes each cocktail with care. The entrance requires climbing stairs up to the third floor.
