For dinner we often end up at Taverna tou Psiri. They have a garden in the back. This was one of the first tavernas in Psiri, in fact it was open during the German Occupation
in WWII because there is a story about it. If you come order the Paidaikia. If they are full go to the taverna next door or my other favorite Oinopoulion tou Kokora.
You can read about them on my Restaurants Page in the Psiri section. Because I stay at the Hotel Attalos this is the area I know the best, at least food-wise.
