I go every year. I have for a long time. The older I get the more I like it because I can actually afford to buy something other than food now. I like to go there for lunch. I especially like the gyros and lemonade. Id really love to try the chocolate dipped cheesecake on a stick. Guess I should have done that when I was younger and could afford the calories.
If you can't afford the art you can usually find some good bands to listen to for free. In addition to food I've bought pottery, clothes, and jewelry there. What's not to love about a festival with yummy food and jewelry!
