Thanadsri Svasti

Mom Rajawongse Thanadsri Svasti (Thai: หม่อมราชวงศ์ถนัดศรี สวัสดิวัตน์, RTGS: Thanatsi Sawatdiwat, 28 May 1927 – 27 August 2019) was a Thai writer, singer, broadcaster and actor, best known as a culinary expert and for his food writing, especially the "Shell Chuan Chim" (เชลล์ชวนชิม) food guide.

Thanadsri grew up in the royal Sa Pathum Palace, and was attending university when World War II disrupted his studies and led him to join the renowned Suntaraporn band. As a singer, he recorded over 200 songs. He had a brief television acting career, before becoming known as a food columnist—"Shell Chuan Chim" was extremely influential and propelled the businesses of many restaurants—and a radio and television presenter. In recognition of his musical career, he was named a National Artist in performing arts in 2008.
