A periptero/kiosk is such a permanent feature on the Greek streets. Not only can you make a call, buy cigarettes, drinks, sweets and telephone cards. It is also a place to leave keys, to exchange money, to leave money and messages for other people and ask for advise. I (Daphne) admire the people who work there almost 24 hours every day and who are always willing to help you if you have a problem. If everything is closed you will find what you are looking for at the periptero!
