We asked spontaneously if they have an escape room which is available right now, and they gave us their best room which was about a serial killer. The room was so good and so completely different than any other escape rooms I've done before because it was so realistic, you really are trying to get out before the killer gets you.
At the venue there is also e very nice bar with fantastic drinks. From outside, it is not very clear what can be discovered in the inside, so it is a truly hidden gem in Budapest. I would go again immediately!
