Naked & Hidden Faces is a masked naked night at Achilleus: from 18:00 until closing every guest covers their face completely with a balaclava or a mask, and nobody wears a towel round the hips. The terrace is the only place where the mask may come off.
Phones are banned in every area from 18:00. Anyone who does not want to follow the two rules leaves at that time. Masks can be rented or bought at the counter.
