For Lotteria the 29th is "Niku no Hi" 肉の日 or "Meat Day", because the number 29 can be read with the same pronunciation as meat "niku". For three days, the weekend plus the 29th, Lotteria is offering special versions of its premium burger, the zeppin burger 絶品バーガー or "masterpiece burger". The special versions consist of burger patties containing 1.5 percent more meat, double the amount of cheese (two slices of cheese made from Gouda and red cheddar), and extra chewy buns made with yeast cultured in rice malt 酒種. And for those who really need a meat rush, there is double patty version.
