The Uzu no Oka Onaruto Bridge Memorial Museum in Minami-Awaji City has begun selling the "Awaji beef-wrapped hamburger steak set meal" (1,650 yen including tax), which is made with Awaji Island ingredients. A new storefront has been opened within the facility, and the food is prepared right in front of customers. The new restaurant will focus solely on this menu for the time being. Uzunokuni Minami-Awaji, which operates the memorial hall, planned the new restaurant in an attempt to make tourists aware of the deliciousness of Awaji beef. The restaurant is named "Awaji Beef Rolled Hamburger Steak Today is Meat Day. Slices of A5-ranked, top-quality Awaji beef are wrapped around a combination of Awaji beef and pork, and grilled over binchotan charcoal to bring out the flavor of the meat. The onion sauce under the hamburger steak and the onions in the "onion sauce" are of course locally grown. The rice is refillable, and the miso soup contains shiitake mushrooms and other ingredients grown at a welfare facility in the city. Raw eggs are also available, and can be eaten with hamburgers as well as rice with eggs.
