Sorry for the short notice, but there is a Greek Festival going on this weekend (yesterday through Sunday) at Annunciation/Evangelismos Church on Bustleton Avenue (Bustleton and Levick Sts) in Northeast Philadelphia.
This festival has, hands down, the best Greek food of any of the festivals. It's a tiny church, but they know how to cook. The gyro's are the real deal, shaved, not the pizzeria strips cooked on the grill. Enjoy!
