Went to the Logenhaus with a friend on a Saturday night. Luckily it was early and we were seated immediately despite not having a reservation...The place got busy very quickly with lots of people having to sip their drinks while standing. Anyway the place is really cool, with a retro vibe given by the vintage furniture (chintz armchairs, sofas, wood and wallpaper, a piano even!), low light, music and dressed-up staff. The cocktails are very nice and original. There is a whole separate list for gins. You cannot have dinner or food, just drink. If I had to find a defect, I would say a bit pricey; nevertheless I think it\s worth it.
