On our honeymoon in Greece last month, (Thessaloniki, Kavala) every place we went brought out a bottle of water without being asked for it, but it was usually only 1 Euro or less, and as I am literally unable eat a meal without cold water (no matter what oher beverage I might also be drinking with my food) I didn’t mind.
Incidentally, I can’t say enough good things about the food & wine in Greece. I have spent time in over 15 different countries in Europe in ust the past 3 years, but Greek cuisine is simply incredible; Fresh, highly flavored, generous portions and extremely affordable by (“Western”) European standards.
