All alone in Athens this weekend. Any ideas?

Hello Athens people! I happen to be here for the whole weekend on my own just to find out the city is semi-dead due to the celebrations. Any recommendations on what to do and where to go today and tomorrow? Have booked a walking tour for Sunday morning, but this will keep me busy just for a couple of hours. It is not my first time in your beatiful city, so all the museums are already ticked.

Anybody up for a drink or cinema tonight? :)

Evharisto poli!
