If you really want to go out for Greek food when in Paris, where to go? Evi Evane is one of the places. Despite the very central location around Saint Germain and Mabillion, the place is very reasonably priced and things are good. Like in Greece: Not sophisticated or extravagant, just simple and well prepared. A very nice and cosy place. Challenge yourself and try the greek wine - it's actually quite decent.
