I was thrilled to learn that Yvonne Chan, whom I haven’t seen in ages, was going to be in Bangkok. Now at Kwant Mayfair London, she was taking over ABar Rooftop Bangkok, offering four exciting cocktails. Green Park features a blend of Don Julio, Empirical Ayuuk, avocado, yuzu, lime, and agave. Wallet showcases Johnny Walker Black Label, miso, barley vermouth, salted maple, and chestnut. El Camino presents Ron Zacapa XO, red currant, coffee, triple sec, and Peychaud’s Bitters. Cosmo Highball combines Tanqueray No. 10, cranberry, Paragon Timur Berry, oat, green cardamom, and citrus. Yvonne also fixed me a mysterious special drink for me before the night concluded.
