Please note that The Making of Harry Potter Experience is very difficult to book so I recommend making reservations as soon as possible.
This experience is outside of Central Tokyo (15 mins on the train from Ikebukuro) at Toshimaen.
Gluten free options at The Making of Harry Potter Experience:
There is a small hamburger steak, rice bread and a few sides meal that is gluten free.
See here for a full write up on The Making of Harry Potter Studio Tour in Tokyo.
They also have many sections of the studio themed for Christmas in November and December. See here for other ways to celebrate Christmas in Japan.
