This funky restaurant’s name was inspired by its address, on one of the main streets in the Athens district known as Neos Kosmos, or New World. It could just as well be called Terra Incognita, so distant is it from the usual areas frequented by locals and foreigners alike for entertainment and good food. And yet, geographically, it’s just a short walk from a new institution that has already claimed its rightful place among the “must sees” of the Big Olive: the National Museum of Contemporary Art.
