As the title says, looking for a real Greek resto, not fkn Sum Tum Souvlaki.

I haven't been to the restaurant, but I order takeout from Aesops, and the food is good. It's not the best I've ever had, but it's definitely much better than anything else I've found here, especially the Kleftiko.

Hmm, I'm on the lookout for some good moussaka.
