1) Ayana Resort & Spa - Rock Bar. This place will make you happy with its outstanding service, cocktails and the best sunset you can witness in Bali. Make sure you reach there by 4:30pm so you can chill for a bit and enjoy the view.
2) is KuDeTa - again this place has its own charm with beach beds, sitting by the pool or just chill by the bar.
3) Potato Head - This place is a retro styled bar, with cocktails and smoothies, you can enjoy the ambience and some quick bites.
Well, Bali has a slow paed life, not much chaos around you, lets you unwind, soak up the sun by the beach, and relish those well known cocktails. But for those poor non-vegetarian people out their make sure you mention you do not prefer any pork or beef by the side in your dish, provided you are ready to try some novelty.
