The Mandarin Oriental and Peninsula hotels offer prime riverfront locations for leisure tourists in Bangkok, but for business travelers and serious shoppers, The Sukhothai’s setting in the commercial and diplomatic district can be more convenient. One of the chief draws of this six-acre resort is its gourmet Thai restaurant, Celadon, set in a temple-like sala surrounded by lotus ponds. It presents beautiful renderings of local dishes throughout the year, but if possible, gourmands should plan a stay when a notable guest chef takes the reins: February 1-4: Alfonso Iaccarino of Don Alfonso 1890 (two Michelin stars). March 6-10: Gaetano Trovato of Arnolfo Ristorante (two Michelin stars). April 24-29: Alain Passard of L’Arpège (three Michelin stars). October 23-27: Iniaki Aizpitarte of Le Chateaubriand (ranked #9 in San Pellegrino’s list of the world’s top 50 restaurants). November 14-17 or 21-24: Andrew Fairlie of Restaurant Andrew Fairlie (two Michelin stars).
