Café Abyssinia in Monastiraki

There's no better place to be on Sunday afternoon in central Athens than Café Abyssinia, when the little red tables at this family-run institution spill out into the street, giving a front-row view to the colorful chaos of the city's best flea market. No one who's anyone hasn't had lunch here, so sit back and order another carafe of wine, listen to the accordions and gypsy singers, and feast on food that nods its head to Greece's Middle Eastern ties: couscous with chutney, roast chicken with cumin, and grilled haloumi cheese from Cyprus.
