Hotels with rooftop restaurants: four of the best Banyan Tree, Bangkok There has long been a debate about which Bangkok rooftop restaurant is the best: Sirocco, which claims to offer the highest al fresco dining experience in the world, on the 63rd floor of the Dome at lebua, or Vertigo, on the 61st floor of the Banyan Tree Bangkok. While Sirocco, which is by the river, is slightly higher, Banyan Tree is more central, at the heart of the business district, so the views are even better, taking in both river and city. Expect to be offered seared bay scallops, roasted snow fish and tenderloin Wagyu - and refreshing cocktails such as a Vertigo Sunset (Malibu, pineapple juice, cranberry juice and lime juice) at the adjoining Moon Bar. If you are going to stay at the hotel, try to book a bedroom as high up as possible, as all have floor-to-ceiling windows that offer the most amazing views. There is also a very good award-winning spa, a health club and an outdoor swimming-pool on the 21st floor. While you are not right next to the river, you are not far away, so be sure to join one of Banyan Tree's nightly Apsara gourmet river cruises.
