[What] You can get Shake Shack's "Shroom Burger" for free! First 500 people at Shinjuku Southern Terrace Square

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.
