Fast food chains in Japan somehow love to create “heart-attack inducing” hambugers as promotion (Windows 7 Whopper and Mega Tamago). Now its Lotteria turn and they are allow customers to stack their Tower Cheese Burger 「タワーチーズバーガー」with 10 pieces of patties for 100 yen each.Essentially, you’d start off with a 160 yen cheese burger and create a monstrous burger seen above which weighs a little more than half a kilogram (579 grams).
Actually it’d be cool if you had a large family, then you can just order one really large burger and share it together for a satisfying meal.
