J. Boroski

Tucked away in a quiet alley off Thonglor Soi 55, J. Boroski is a clandestine gem where famed mixologist Joseph Boroski creates tailor-made cocktails according to your tastes—no menu required. With design contributions from Ashley Sutton, the décor blends dark minimalism and artistic metalwork with candlelit warmth, creating an intimate ambiance ideal for date nights or solo evenings. Patrons describe it as “cozy yet fancy,” with soft light, plush seating, and quiet sophistication. The signature experience begins as you share your flavor preferences; bartenders then engineer a unique libation using global ingredients—think butterfly-pea extracts, mangosteen, house-made bitters, and exotic spirits. Each cocktail is a surprise crafted for you. Reviews consistently hail it as one of the best cocktail bars in the world. One guest exclaimed, “Hands down, the best cocktail bar I've been to in the world! … The man himself… made individual masterpieces… we felt like we won the lottery!” Despite its exclusivity, others caution about the high price—expect to pay Bangkok-evening-drink rates matching global hotspot standards. While there is no formal website for reservations or menus, some guide services (e.g., on Facebook or via contacting in advance) help provide directions and access. Open nightly from around 6:30 PM to 3:00 AM, it’s recommended to plan your visit to avoid disappointment.
