This year, the event will be headlined by high-profile chefs Sompong, Satawat Kunarasai, and Surasing Viratsakul, who will lead cooking demonstrations and prepare three- and four-course dinners comprised of organic ingredients. The festival also incorporates the rotating farmers market on Saturday and Sunday. The cost to take part in the cooking demonstrations, which include lunch, coffee and tea, soft drinks, an apron, and a recipe book, is B1950 per person. Dinners, including welcome drinks, soft drinks, and free-flow wine, coffee, and tea, cost B2500. Afternoon activities and the farmers market are free of charge. A portion of the proceeds go to the FOOD4GOOD programme, which assists malnourished children living in Thailand. For more details, visit facebook.com/rivasuryabangkok.
