The back of the coupon gives a detailed description. The restaurant is located in Room 1002 of a building decorated like a European castle.
The room is huge. Room 1002 is the dining area, and there are other activities nearby, such as an escape room.
My uncle is interested in the occult, but everyone else is completely clueless. We talked on the way there about the escape room in the castle. It would probably have a Western theme, and if it was a horror escape room, it might be demon-themed. My uncle and I would be the ones taking the lead.
