Queens Pita on Main Street in KGH has the best I've ever tasted. Went on Friday morning at 815 AM and they had people lined up 20 deep to pay (line snaked around the store).
All donuts are sold in boxes of 4 for $8. The nutella flavor is the best by far. They also do halva, pistachio, chocolate, jelly, custard, cream and caramel.
