I ate Burger King "Double Cheeseburger". It contains 2 pieces of patties and 2 pieces of cheese. But it's not tedious.
Double cheeseburger is 400 yen (tax included, same below). A set of French fries (potato) M size and drink M size is 600 yen. It seems to be available for a limited time.
Two 100% beef patties and two pickles, ketchup, mustard, and two thick cheddar cheeses are sandwiched between sesame buns. It's a simple and straight hamburger, and although the cheese is chewy, it doesn't leave much behind and doesn't leave much aftertaste.
Patty tastes like roasted beef and feels like Burger King. When you bite it with soft buns, the seasoning, meat, and cheese taste together and occupy the taste, so you will feel junk satisfaction. Perhaps because Cheddar doesn't insist too much, I can understand the scent of meat.
The size is also easy to eat, and the impression that you are just full with the potatoes you ordered as a set. On days when you're intrigued by fast-food lunch or dinner, it might be a good choice.
