The mega sushi roll has 20 different types of fish and vegetables wrapped inside 2 meters of rice and seaweed. That's right, 2 meters.
To give you some perspective about just how big the giant sushi is, one slab of tuna that is placed on top of the large rolls would regularly be enough to make 40 average-sized rolls. Be warned, though: giant sushi costs about 15,000 yen and requires a reservation two days in advance. Totally worth it, if you ask me.
