I can't tell you how much fun this is. A group of us did this for my mom's 60th birthday. We didn't know what to expect, but walked away wanting to come back soon and wishing we had one more hour to figure it out the room. You are locked in a room and work together to find clues to get you out. If you have an analytical mind and love puzzles, you must try this.
Unfortunately, we couldn't solve the 70s room, but couldn't stop talking about it. It is a really fun hour and a mental challenge.
