I always enjoy this festival. It's in October so it can be pretty hot. They have lots of shade areas set up. We do the "inside" food because we think it tastes better. The lamb shank is delicious and just falls off the bone. Other favorites include the potatoes and mousaka. The stuffed grape leaves..... not so much.
They run out of Baklava on midday Sunday so be sure to purchase on arrival. The nice ladies will hold it for you so you don't have to tote it around the grounds. We inevitably try on the Greek Fisherman's hats or a T shirt, or jewelry, and always find something to buy. It's a fun afternoon listening to live tunes, eating great chow and getting in touch with my inner Greek.
