We are flying to Athens tomorrow, arriving midday. I was wondering if there will be shops and restaurants open in Monastiraki- Thisio - Acropolis area tomorrow that the referendum is happening. We are leaving Athens Monday morning to take a cruise ship. I was told it's not a good idea to walk around syntagma area tomorrow night (our hotel is right behind syntagma) because after the announcement of the result there might be riots. Thoughts?
