Avoid the tavernas in the Plaka like the plague, it's a nice enough area, rather like being in a village within the city, but unfortunately now it has become overrun by tourists, and eating out there has become a bit of a rip off.The restaurants in the centre, like any capital city are pricy, but look carefully and you’ll find some great places just a street or two away.
Monasteraki market is worth a visit ( and a tube station) especially for leather sandals.
Follow the locals and eat where they eat, that's my tip.
