Wow, the artworks here are amazing! 
I agree. - Can you take a photo of me, please?
- Sure.
- Thanks.
- And where’s the nearest CR here?
- There’s one in this floor. I think it is out of order.
- So you have to go upstairs. Take this way, then turn right then you’ll see the stairs.
- When you are at the second floor, turn left until you reach the CR at the end of the hall.
- Thank you.
CR
："CR"は"comfort room"の略で、"toilet"の意味。「お手洗い」
