Taking advantage of Japan’s confectionery-obsessed culture with the joy of sitting around a small table and making your own food, start an ice-cream okonomiyaki* dessert house. Instead of grilling their food, patrons could mix and mash premium ice-cream flavors with a variety of toppings and sweet fixings on a cold stone. It would be like Cold Stone but different for legal reasons.

Pro’s: Big potential market. Japanese women would sell their own for a scoop of sherbet.

Con’s: Salmanilla.

*Okonomiyaki is a traditional Japanese savory pancake that can be filled with a variety of ingredients like cheese, spring onions, kimchi, shrimp or what-have-you and topped with mayonnaise, fish flakes, and brown sauce. It can be bought on the street at festivals or at okonomiyaki restaurants – where customers sit around grill tables and cook their own okonomiyaki, which, when finished, is served in slices. It’s like a pizza but with brown sauce.
