Went there on a first date and really got to get to know the other person solving puzzles with them.Bwiegelm
It was a lot of fun. Some of the puzzles were a little more challenging than I expected but they have a great hint system that helps exactly as much or as little as you want.
Will definitely return and try the other rooms.
