YABAR Secret Bar & Rooftop is a hidden rooftop cocktail bar in the Khao San area, tucked above Olive Kitchen on Trok Bowonrangsi. You reach it through a secret door that gives the room its name, and the interior opens into a neon-lit, whimsical space that leads up to an intimate deck looking out over the rooftops of Phra Nakhon.
The bar trades on novelty without losing the drinks. Cocktails arrive with theatrical garnishes and playful vessels, and the two-floor layout is stitched together with quirky features including a slide between levels and a jumbo Jenga set near the bar. YABAR opens nightly at 6:30 PM and runs until 2:00 AM, and the dress code stays smart-casual rather than velvet rope.
It has become one of the more talked-about rooftop bars in the historic side of town, averaging a 5.0 rating across roughly 850 Google reviews. Most of the clientele are Khao San travellers and a younger Bangkok crowd looking for a rooftop that is not in a Sukhumvit hotel tower.
Finding the entrance is part of the visit. You walk up from street level, push through the hidden door above Olive Kitchen, and step into a neon-washed interior with quirky signage and soft colour. Staff will usually point you toward the slide or the stairs if you want to go up to the roof deck, where the seating is casual and the view stretches across the low-rise Phra Nakhon skyline.
Service is relaxed and conversational. You order at the bar or from a server on the deck, drinks come out with a lot of visual flair, and the space stays intimate rather than club-loud. Expect a mix of couples, small friend groups, and backpackers who have crossed over from Khao San Road for something quieter than the street.
The Swag Duck in the Bath is the drink people come for, a cocktail served in a bathtub-style vessel with a rubber duck floating on top as the garnish. East Asia sits on the house craft list as one of YABAR's signature builds, and Mom Mao is another of the regulars, delivered with the same theatrical presentation that runs through the menu. Beyond the signatures, the cocktail list leans into bright colours and oversized garnishes, and the interactive touches on the ground floor, including the slide and the jumbo Jenga, double as photo moments between rounds.
YABAR Secret Bar & Rooftop sits on Trok Bowonrangsi in Chana Songkhram, a short walk from Khao San Road and the Phra Athit riverside in the historic Phra Nakhon district. There is no BTS or MRT station nearby, so most guests arrive by taxi, tuk-tuk, or on foot from Khao San; the Chao Phraya Express boat at Phra Athit Pier is the closest public transport option.
