I was only two days in Athens and I took the mythological tour and the food tour. Both were excellent! The mythological tour was very informative, the guide, Alexandra, was very knowledgable and we covered all the major sites. The food tour was excellent, in addition to tasting many Greek delicacies, you learn about the stories and the culture around the food, which is a great way to learn about Greek society. We went to traditional coffee houses, to the market, to more modern pastries stores, tasted the most delicious olives ever, etc. I fully recommend both tours to any one going to Athens that does not want to take a super touristic tour but still get to know the city and their people. I loved Athens, hope to be back soon.
