The Zeppelin Bar & Restaurant is one of a few roof top cocktail bars in Bangkok. The bar does not sell draft beer but only in cans. The view of Bangkok is not half bad but considering the price it is reasonable. The bar is located on the 46th Floor of the Luk Condo Complex in Phra Khanong.
If you are looking for a night out then go just before sunset as the views are really great! If you are staying at the Jasmine Hotel in Bangkok then this is a short walk away. As stated go early or ask them about a booking (+66 2 348 9121) if you don’t want to miss out on a great evening. There is also the Skytop Bar in Bangkok if the Zeppelin to not scenic enough for you.
