To Triantafilo tis Nostimias restaurant would be impossible to find if someone didn’t tell you it was there. Although just a five-minute walk from busy Syntagma Square, it is hidden in an arcade on the rather unappealing Lekka Street. Despite the central location, the downtown Athens standout remains largely unknown and is not even included in most Athenian food guides. You truly have to be a local to come here.
