My Grandmother makes the best Greek food around, but since I can't always get her home-cooked food, I love the Mediterraneo Market.
This little cafe offers items to go, indoor dining or outdoor dining (which is great during Spring!). Their food is great and they even sell Greek olives and cheese by the pound.
If for no other reason, go because they sell baklava. This little cafe is hidden on a less traveled street, but it just adds to the cafe's character; it's quiet and calming.
