In town I would say on top of Foto pizza, great view, great breeze,great price 3.5TL large Effes (I think)
Out of town on the Kalamar road it would have to be Obi's pancake house. Sit over the road under the trees, looking out over the bay enjoying the breeze. Andy and I used to go there quite a lot for a light lunch, nice and cheap and only a minute from our hotel!
For an iced coffee, Cafe del Mar on the road to the harbour, exotically decorated and great chilled music. I believe they do Effes too but have no idea of the price.
