Beware: if you're walking around drunk in Zurich and seem to be a security-risk, endanger yourself or disturb others, the police might take you to the new drunk tank, come next Friday.
Information here, via NZZ:

The article notes that you have to pay for the stay yourself: 600 CHF for the first three hours, 950 after that.
Might as well check-in to the Dolder ;-)
