Start a game with 4 controllers and go the the sushi bar. Place your main character in front of the exit door then with an other one make him collect the sushi he need to escape. You can see which one you need in the top right corner. After you got them all the door will open so take him in front of it and punch him with your main. Repeat with the other two.
I know for sure you can't do it with only 2 controllers because I played with only my sister before trying this method and it did not worked.
