Clement Piquet, a partner of magazine Food and Wine, was among those that toured popular sites in Chengdu and is a fan of Sichuan cuisine, believing it to be the most delicious food in the world.

"Chengdu is not only home to many renowned chefs, but also attracts top chefs from around the world," he said.

Jiao Tong, a food writer from Taiwan, said for those obsessed with food, a pilgrimage to Chengdu is a must.
