This is a popular “themed restaurant”! The Lock Up, as the name says, is a restaurant where the customers are prisoners and each room is designed to give you the feeling that you are behind bars.
This place scares you from the start! When you open the entrance door, there is a loud alarm sound to scare you. The workers here welcome you in cosplays ; the policeman/woman attend you to the seat, while the prisoners serve you.
The policeman puts handcuffs on you and take you to your room.
Tina and Alisa (from Tokyo Girl's Update) had the Monster Parfait. This was around 40 cm tall, and it was delicious.
All of a sudden, the whole restaurant became pitch black and spooky music starts to play. There are around 10 patterns of scary voice sounds played in the shop, like a voice a little girl looking for you.
This is the popular performance at The Lock Up ! Not only are you a prisoner, but at this restaurant you can experience a new collaboration of a haunted house and restaurant.
Even though I already knew what was going to happen, it was very scary!
