The fourth Japanese hamburger restaurant "Shake Shack" from New York will open in Shinjuku, Tokyo in the summer of 2017. To commemorate this, a pop-up event will be held from May 3rd to 5th, where hamburgers will be provided free of charge.

The event starts at 11:00 each day. The place is Shinjuku Southern Terrace Square. The popular menu "Shroom Burger" will be provided free of charge to the first 500 people each day. A unique burger made by wrapping three types of cheese in a portobello mushroom and fried, sandwiched between buns with vegetables.

The shroom burger will be exchanged for a ticket affixed to a wall with a total length of about 13 meters that appears in Shinjuku Southern Terrace Square. Only one can be used per person. It will end as soon as it runs out.
