The popular San-X character Rilakkuma was first launched in 2003, and to commemorate his 20th anniversary a special pop-up café event is being held in Tokyo.
The Rilakkuma 20th Anniversary Café will include a variety of themed eats on offer, including a Rilakkuma honey mustard hamburger steak plate, a Korilakkuma cream pasta, a Kiiroitori egg burger, or a Chai Roikoguma cheese curry (all priced at ¥1,870 including tax).
The drinks and desserts are also themed, with cakes, parfaits, sodas, and floats available to choose from.
If you'd like a tangible souvenir from your café experience, they've got you covered there, too – a variety of limited time merchandise including tote bags, plush toys, and keychains are up for grabs.
As for the address, if it's asking for that when you register I'd recommend using your hotel/accommodation in that field.
