It was announced on the official Instagram account that "PREMIUM Tsubame-style hamburger steak" and "PREMIUM Japanese-style hamburger steak" are now on sale at Tsubame Grill's online shop "Fresh Tsubame-bin".

PREMIUM Tsubame-style hamburger steak uses Kumamoto Aka beef sirloin as beef stew sauce. It is said that red beef has more lean meat than Japanese black beef, and especially sirloin can feel the taste of Japanese beef more strongly than other parts. By simmering as a beef stew, the taste is condensed in the sauce. Meat with sashimi can be tasted even softer by stewing.

PREMIUM Japanese-style hamburger steak is a special specification with plenty of beef added to the pate. The addition of red beef makes the original texture, umami, and aroma of Japanese beef stand out. The handmade Japanese-style sauce and grated daikon radish make the taste even more appealing.
