Don't be mistaken, this is not a tourist spot. It is a local grocery store which just happens to be in a highly touristic area. Stamatis, the founder, knows almost everybody's preferences in the neighbourhood, so he is really good on guessing your needs. My favorite picks are the goat cheese with pepper, the wholegrain rusks from Crete, sesame paste from Limnos and casaresse traditional pasta. Not to mention the wines, olive oils and honey. Definitely a stop to pick greek goodies.
