O Thanasis is an eatery on a corner of Monastiraki Square. It boasts a short menu of authentic Greek dishes. It also claims to be the oldest restaurant in Athens.
It is my go-to when visiting, and from the looks of the crowd, an opinion shared by many.
Gyros, souvlakis, kebabs, salad . . . they have it all . . . and at good street prices.
Still my beating heart.
