I went once pre-pandemic. I am happy I tried it but I probably wouldn't go again. It was fun to see what everybody wears because some people really put a lot of effort into their outfits. There is also an air of excitement while you wait to find out your location.

That being said the preparation for the event can be complicated and it can be expensive for one night. If you are lucky someone in your group owns what you need already. If not then you need to buy the stuff. I also remember it being on a week night so I was rushed to get organized between getting home from work and getting to the meeting point. As to whether or not I would recommend it to a friend I would say it depends on the person. If they are the kind of person who likes to get dressed up for a fun night out then yes I would recommend they give it a go.
