I went with two friends and we were paired up with another couple - thank goodness, because the game is super hard! We did the laboratory room, which is the hardest. The clues were really clever and everything was perfectly bilingual. The staff were varied... some seemed to really get into their role and others seemed bored. They told us we could take pictures of ourselves after and go find them on their facebook page, which is a cool idea but the staff member didn't really hype it.
They have a nice waiting area if you arrive early where you can play foosball and some logic games to get your mind ready for the challenge ahead. I would 100% go again. I only wish we had a little more time in the laboratory to figure out the rest of the clues.
