My family spent 5 hours with George and he delivered an authentic and educational tour of Athens from a chef's perspective. Trained as a biologist and from a medical family, George decided he wanted to become a chef and now he is loving life. Think of a young and handsome Greek Anthony Bourdain - he teaches you about the food through the history and culture of Athens. We were six people including a child with Celiac disease. When we did the olive oil tasting with fresh Greek bread, he brought my daughter six little spoons so she could have the whole experience with the rest of us. He is fluent in English and knows the entire history of Greece from ancient times to modern days. You won't get the romantic version, he is brutally honest and his frank honesty is refreshing in a politically correct world. One important point - he does not make a commission from the proprietors on the places he takes you. You're seeing the best of Athens. He doesn't stick to a planned tour. He will take you on detours based on what you are interested in - like for us buying high end olive oils and other Greek culinary delights. He made our local dinner reservations, wrote down wines to order at dinner, and warned us about all the tourist traps in Athens. This is a MUST DO activity for your vacation in Athens. Ask for George!
