I was once at the Disgusting Food Museum in Malmö, Sweden. Unfortunately, I don't remember the weirdest thing I ate there (they have some samples you can eat at the end but not for everything) but I remember one of my friends throwing up. They had to reset the counter of days since somebody threw up.

The bugs were pretty easy to eat. They were just very dry and basically turned into dust in your mouth. But they also had some cheese (?) that just smelling it made you want to throw up. The smell was worse than the taste though.
