SIN Rooftop Bar ซิน รูฟท็อป บาร์

SIN is the open-air bar on the 27th floor of the Avani+ Riverside, the roof above SEEN. It opened in November 2024 as the hotel's nightlife floor, with its own glass lift to the top, room for about 80 seated or 180 standing, and resident and guest DJs who turn the terrace toward disco and techno later in the night. Time Out's Thai edition puts the minimum spend at 5,000 baht per table, not per person, and suggests coming as three or four to split it; entry is 18+, and men need long trousers and closed shoes. The cocktail list is ten signatures by head mixologist Brian Gonzalez Fernandez, five of them also made alcohol-free, with names such as Forbidden Nectar (bourbon, miso, caramel) and Midnight SIN (cognac, whisky, cacao, cold coconut coffee); the food leans Japanese with Gillardeau oysters, caviar, Miyazaki wagyu tartare with uni, sashimi and a sharing SIN Mystery Box. No page publishes drink prices. Hours are not settled: Time Out's Thai listing (April 2026) gives Wednesday to Sunday 17:00 to 01:00, closed Monday and Tuesday, while Thailand Magazine and Time Out's English page say daily, so call before an early-week visit. The free hotel boat from Sathorn Pier at BTS Saphan Taksin runs every half hour until 23:15, with the last return at 23:00; boats from ICONSIAM run between 12:25 and 20:25, at a frequency Thailand Magazine gives differently on two pages.
