Arrived at McDonald's.

In front of the shop, there was a poster of the double beef double cheeseburger. I immediately ordered the double beef double cheeseburger (420 yen including tax) and the regular 'double cheeseburger' for comparison.

On the left is the new 'Double Beef Double Cheeseburger,' and on the right is the regular 'Double Cheeseburger.'

The double beef double cheeseburger looks like this. It's thick with four patties.

Compared to the long side of the iPhone 7, it looks like this.

If you line up the new 'Double Beef Double Cheeseburger' on the left and the regular 'Double Cheeseburger' on the right, you can see that the 'Double Beef Double Cheeseburger' has two more patties than the 'Double Cheeseburger' and is thicker.

The filling is the same as the regular 'Double Cheeseburger': ketchup, pickles, onions, cheese...

And four patties.

When I tried it, I found that it was so thick that I had to open my mouth as wide as my jaw could to eat it, and the volume of the beef in the patty was perfect. The flavor of the beef was superior to the flavor of the cheese due to the four patties.

The Double Beef Double Cheeseburger is a 9-day limited menu item available until Wednesday, February 7, 2018, and is available at McDonald's stores nationwide, except for some stores. The single item costs 420 yen (tax included), and the value set, which includes one drink and one side dish, costs 720 yen (tax included).
