Bangkok’s cocktail scene showcases a rare cross-over between Firefly and OXBO at SEEN

On 3 September 2026, Bangkok’s vibrant bar culture will be highlighted by a unique one-night collaboration as Firefly’s Mart and OXBO Bangkok’s Gilang Pangestu take over SEEN Restaurant & Bar, offering a contrasting glimpse into the city’s diverse mixology styles with exclusive drinks and skyline views.

Bangkok’s cocktail scene will get a one-night crossover on Thursday, 3 September 2026, when Firefly’s Mart and OXBO Bangkok’s Gilang Pangestu take over the bar at SEEN Restaurant & Bar on the 26th floor of Avani+ Riverside Bangkok Hotel. The event is set to run from 6pm to 11pm, with entry free, making it an easy add-on for travellers who want a polished night out above the Chao Phraya River. According to the announcement, the pair will serve drinks created especially for the occasion, with each bartender bringing a different style to the same counter.

For anyone planning a Bangkok bar-hopping trip, the draw is not just the guest shift itself but the contrast in setting and style. Firefly at Sindhorn Kempinski Bangkok is known for its dark-wood, moss-green interiors, live jazz and smart-casual, late-night feel, while its cocktail programme leans towards classic technique with local ingredients. The bar has also been recognised in Asia’s 50 Best Bars, giving this collaboration an added sense of pedigree.

SEEN, meanwhile, offers a very different backdrop: skyline views, river light and a more open, high-rise energy suited to music and mingling. The organisers say Mart and Gilang will alternate behind the bar through the evening, so guests can compare two approaches in one sitting rather than choosing between separate venues. For visitors who like to explore Bangkok through its bars, that makes the night more than a simple guest shift; it becomes a compact snapshot of the city’s current cocktail culture.

Reservations are available via the hotel’s riverside dining contact details, though walk-ins are also being welcomed. For travellers staying near the river or looking for an evening with a view, it is the sort of one-off event that rewards advance planning, especially if you want to linger for the music as well as the cocktails.
