■ Protecting the legacy of the old establishment and pursuing even greater deliciousness
Born in 1952 in Shinkaichi, Kobe, "Grill Ippei" celebrates its 70th anniversary this year. In a town that once flourished as a mecca of entertainment, what has been passed down from the first to the fourth generation is not just a recipe, but the "passion for our customers" put into every dish. Until now, we have restricted our offerings strictly to dine-in to protect its delicate flavor. However, responding to the voices of fans nationwide who said, "I want to send this taste to a loved one far away" or "I want to slowly enjoy the taste of a famous restaurant at home," we have finally decided to sell it in frozen packs.
■ Product Features: The sauce of "life" that takes 5 days
1. The restaurant's synonym, a "demiglace sauce" filled with about 70 years of history and passion.
Grill Ippei's demiglace sauce requires a total of 5 days to complete. Extracting the umami of vegetables and meat to the absolute limit, the rich depth where bitterness and sweetness are perfectly balanced is a craftsman's dedication that has remained unchanged since our founding.
2. In-house ground hamburger steak overflowing with meat juices that complements the sauce.
We use fresh meat ground in-store. The meat juices that overflow the moment it is baked mix with the secret sauce, creating a blissful taste that makes you want to drink up every last drop.

──Aiming to be a beloved Western-style restaurant──
We are a well-established Western-style restaurant in Kobe founded in 1952. Centered around female entrepreneur Kan Yokoyama, we opened for business in Shinkaichi, which was such a mecca for entertainment at the time that it was called "Asakusa in the East, Shinkaichi in the West." Under the second generation, we were hit by the "Great Hanshin-Awaji Earthquake" on January 17, 1995. We were forced to face the choice of closing down due to the collapse of the store, the evacuation of employees, and the difficulty of securing ingredients. However, supported by the kindness of regular customers who said, "We don't want to lose Grill Ippei" and even built a prefabricated store for us, we pushed forward, led by the third generation, and achieved a revival. In 2011, the recipes and passion inherited from the first generation were passed on to the fourth generation. Valuing the attitude of protecting tradition while pursuing further deliciousness, we will continue to do our best so that more customers can enjoy the taste of Grill Ippei.
