The guy that I share an office with, Kostas, sends his daughter to the Hellenic American Academy on Saturdays to learn the ways of her Greek heritage. Anyway, they have a Greek fest every year on Labor Day weekend in Deerfield. If you want to enjoy some Greek food, music, etc. and have the time, you should check it out.
