All’Antico Vinaio has introduced a limited-time sandwich collaboration with social media chef Owen Han, widely known online as the “King of Sandwiches,” blending Italian tradition with modern, internet-driven food culture. The collaboration introduces La Mediterraneo, a specialty sandwich inspired by Han’s Italian-Chinese heritage and his minimalist, flavor-forward cooking style. The sandwich debuted on Wednesday, January 24, and will remain on menus for one month at all All’Antico Vinaio locations everywhere. His collaboration with All’Antico Vinaio marks a crossover between viral food videos and a globally recognized Italian sandwich institution. All’Antico Vinaio, founded in Florence, is known for its oversized schiacciata sandwiches and has opened several restaurants in Los Angeles in the last two years.
