Fancy a Freddo or Frappe? Try Athens’ Clemente VIII

Whether you fancy a Nescafé frappé (thick, grainy elliniko) or a freddo (cappuccino or espresso blended with crushed ice), make sure to stop at Clemente VIII. As hip as Brooklyn's own Williamsburg, expect this cafe to be packed with Athenian trendsters and coffee snobs (not only is the coffee spectacular, but the people-watching mesmerizing).
