On their way to Keicho's grave, Josuke and Okuyasu come across an Italian restaurant called Trattoria Trussardi, run by Chef Tonio Trussardi, who makes dishes based on the observations of his customers. Upon trying each of Tonio's dishes, Okuyasu experiences violent reactions within his body, such as his eyes being squeezed of their moisture and his teeth launching out, only to find they have ultimately benefited him by curing his various maladies. Growing suspicious, Josuke discovers that Tonio had been supplementing his dishes with his Stand, Pearl Jam, and confronts him. After a brief scuffle, Josuke discovers that Tonio had only acted hostile towards him for not washing his hands before entering the kitchen. Tonio reveals that he simply wants to help his customers. He explains that he senses maladies his customers may be ailing from, and creates dishes that he infuses with Pearl Jam, which heals the customers' maladies and improves their health. Tonio then puts Josuke to work scrubbing the kitchen for his actions. Meanwhile, Jotaro meets with a representative of the Speedwagon Foundation, who informs him Joseph Joestar is on his way to Morioh.
