Concept
The first-season cast members are restaurateur and television personality Hong Seok-cheon, boy band Shinhwa's Lee Min-woo and actor Yeo Jin-goo. Seok-cheon, an owner of a number of Thai restaurants, along with the other two members operated a Thai food truck in cities in Thailand. Their aim is to see if Thai people would eat Seok-cheon's version of Thai food.

The second-season cast members are Korean-Chinese cuisine chef Lee Yeon-bok, actors Kim Kang-woo and Seo Eun-soo, and comedian Heo Kyung-hwan. They operated a Chinese food truck all around China.

The third-season cast members are boy band Shinhwa's Eric Mun and Lee Min-woo, singer John Park with Korean-Chinese cuisine chef Lee Yeon-bok and comedian Heo Kyung-hwan. Jung Joon-young was initially cast for the filming in Los Angeles and Shinhwa's Lee Min-woo was being cast for filming in San Francisco. However, due to Jung Joon-young's involvement in the Burning Sun scandal, the production team decided to completely remove all of Jung Joon-young's footage.

The fourth season, a domestic spin-off of the show named Will They Eat When Delivered (배달해서 먹힐까), stars Italian cuisine chef Sam Kim, television personality Ahn Jung-hwan, and singers Yoon Doo-joon of Highlight and Jeong Se-woon. They operated a kitchen in South Korea (Yeonnam-dong, Mapo-gu, Seoul) and made Italian food. They are only available for delivery through ordering with food delivery applications or calling in to the kitchen to order. The cast members' identities are unknown to the customers, except for the hints appearing on the packages of the food.
