amBar Rooftop, Sheraton Bangkok

amBar Rooftop is a hotel rooftop bar on Sukhumvit that runs a weekly Sunday bachata social — think an open-air terrace with bar seating, skyline views and a small cleared area the staff use for dancing. Reviews and the hotel site identify it as the rooftop bar (guests mention the 8th floor) within the Paradox / Sheraton/Four Points property, so the setup is a cocktail-and-food roof-venue rather than a dedicated dance hall.

The rooftop operates roughly 12:00–00:00 daily and the bachata night sits alongside the bar’s regular drink promotions and private events (networking nights, hosted groups). There’s no clear sign of a warm-up class on the hotel pages; expect a social-DJ or host format, bottle service and a compact floor that fills quickly when an event is on. If you want space to practice shines, plan to arrive early or check the organiser’s post on the hotel’s social feed before you go.
