St. Barbara's Greek Orthodox Church in Orange, CT, will be holding their annual Odyssey Festival this weekend. They have the best Greek food I've been able to find in Connecticut.
Here is the link to the main page of their website:
But this is the page you're probably more interested in:
The food page leaves some things out. The last couple of years they have had saganaki (a pan fried sheet of feta), but they run out of this early in the weekend. Down in with the Greek pastries in the church basement they serve traditionally prepared Greek coffee (analogous to Turkish coffee). There is also a stand outside that serves frappe (a frothy, frozen coffee drink made in a blender from spray dried instant coffee, milk, and ice, with the option of sugar; Starbucks frappuccino is a really poor imitation of this traditional Greek summer drink).
Over the course of the weekend I usually end up eating everything they serve at least once, but my favorites are: tiropita, keftethes, pastitsio, souvlaki, kadaifi, and saragli. I always take home at least one loaf of their tsoureki (a slightly sweet brioche like bread flavored with mahleb) which is fantastic toasted for breakfast.
Make sure to visit both food tents as they have different offerings. Check out the schedule of events before you go. There are Greek cooking demonstrations, live traditional Greek music, and performances of traditional Greek dancing (they have different age groups of dancers with the oldest being in high school, and I think usually the earlier performances are the younger kids, and late performance is the high schoolers). Take a look inside the actual church building while you are there; the artist that painted it is exceptionally talented.
