At Mos Burger, a special event "Meat Day Weeeeek!" Will be held every four years to commemorate February 29 (Meat Day) for five days from the 25th to the 29th of the same month. "Niku Katsu Niku Burger" and "Spicy Niku Katsu Niku Burger", which will be available only on the 29th of every month, will be on sale throughout the period.

February 29 is a leap day that is entered once every four years to eliminate the difference between the calendar and the actual season. Mos Burger calls it Meat Day.

The "Niku Katsu Niku Burger" that will be sold this time is 806 yen (excluding tax, the same applies below). Mos Burger's original loin cutlet and teriyaki chicken grilled on an open fire are combined with green leaf and lettuce, and are sandwiched between patties instead of buns (bread). Thick slices of pork loin are fried crispy and served in a soy sauce-based Japanese-style sauce. Teriyaki chicken is made by grilling a piece of chicken thigh, which is simply seasoned with salt, on an open fire to remove excess fat, and then entwined with teriyaki sauce and grilled twice. The skin is crispy and browned, and the inside is juicy.

The "Spicy Niku Katsu Niku Burger" that appears at the same time is 834 yen. For those who like spicy food, jalapeno (green pepper) is added to "Niku Katsu Niku Burger". A dish that goes well with the umami of meat and the spicy spiciness.

In addition, if you follow Moss' official Twitter account (@mos_burger) and retweet the corresponding tweet, 229 people will win "Double Tobikiri Cheese-Use Hokkaido Gouda Cheese-" (612 yen).

The URL of "Pochitto Gift (electronic gift)" will be sent to the direct message on Twitter. Select the URL, display the barcode on the screen of your smartphone, and take it to the Mos Burger store to receive the target hamburger. Winners will be decided in March.
