The Greek Church on upper 16th St. near Upshur will be having their semi-annual Greek festival this weekend. Delicious, reasonably-priced food, but try to attend at night for the live music. Really good musicians playing bouzouki (sp?), dancing too.
Next weekend, it's the Greek church at 36th & Mass., in the shadow of National Cathedral. Again, great food, great music & dancing, even a moonbounce & crafts for the kids. Last spring they had church tours too.
The church on Bradley Blvd only has 1 fest a year, in May. Not sure if the Greek church in 7 Corners has had their semi-annual festival yet.
