Chubby (pochari) entertainment personalities eat kaiten sushi (conveyor belt sushi) in a restaurant called Sushi Ro- which is slang for Sushi Robot.
Part I: They compete to see who can eat the most! Who can stomach failure? Who will win??
Part II: The police force search for the best improvement on negitoro, a classic combination in its own right.
On a personal note, I am quite pleased with this episode, featuring variations of a few of my favourites - bacon/pork nigiri and grilled beef nigiri. Glad to know that these dishes are widely available.
Translation note/question: Ham is cured, right? So what is the meaning of nama hamu if nama means raw?
