Price: 238rmb/person (during off-season, the price goes down to about 198rmb/person)
How long do they give you: 90 mins
Group size: 4-10 Though it's a little out of the way (you'll have to take a crowded elevator into a sketchy office block near Xujiahui) House of Kaidan manages to deliver with the small space that it has. There are three different themes with budget-creepy decorations and next to no light, creating an unsettling haunted house atmosphere. One is a more traditional escape room, where they separate one member from the party, and have an actual Sadako stalking the corridors. The other two are heavy on roleplay and require a lot of local knowledge. Clues and story lines are all in Chinese, but they said if you book in advance, they'd be happy to find someone who can translate. If your group is small, they might ask you if you could pair up with another group, but you're free to say no. They give you 90 minutes, but it's pretty pricy, about 238rmb/person during peak periods.
