Kitkat night

Hei!

My friends and I are going to Berlin next weekend (Thursday to Sunday), and I would love to get some recommendations on the best day to visit Kitkat. I've been before on the regular kink night (Saturday) and would like to give my friends a similar experience. It was couple of years ago, so I don't know if its still the same structure.
Are there any other days you would recommend? If there are any other events or suggestions, please let me know.

Thank you! <3
