For uninterrupted views of the Chao Phraya River and the city it snakes through, head to this rooftop perch at Avani+ Hotel. Each evening, this wining and dining destination turns up the temperature as skilled barmen carefully mix epic cocktails and DJs spin a hypnotic Latino soundtrack. Head out to the terrace for some obligatory shots before ordering a drink and sampling Portuguese-Brazilian fare created by renowned chef Olivier da Costa.
