Athens Markets/Restaurants

I'm living in Athens for a year and looking for high quality meat, vegetable, and fish markets. I am in Psihiko, and the closer the better, but if there is something spectacular out there I'm willing to travel every now and then. I have been to the central meat, fish, and produce market near Omonia and I was underwhelmed. Any suggestions on fantastic dine-outs, coffee, pastries (turkish/greek, declare your political allegiance so long as it comes with a qualitative suggestion) are also very appreciated. Basically, if you know anything about great Greek food not listed in Rough Guide or Lonely Planet, please share, Cheers, Seth
