Thought people who are spending time in Athens might be interested in this article. Xenokratous Street is on the way up to Lycabettus and the market a good reason to go on a Friday. Both the restaurants mentioned - the Filipou and the Omorfo - are excellent traditional eateries. The Filipou is a particular favourite of ours. We first went there more than thirty years ago and it really has barely changed!
Happy travels
