Hundreds are expected to gather at the Holy Trinity Cathedral and Greek Cultural Center in New Orleans for the 40th annual Greek Festival next weekend. Dozens of volunteers are busy preparing for the event, which will feature authentic Greek food and traditional dancing near the lakefront. As many as 175 lambs will be roasted on the spit. The adventurous types who show up donning a toga will be admitted for free. The one with the best toga will win a prize - a bottle of Ouzo. Opa!
