Here is your chance to get some good Greek food. Attached is a link to a buck off coupon for admittance. If you go before 4PM on Friday and after 6PM on Sunday, it's free to get in.
My faves are the moussaka and the stuffed grape leaves in the dining hall and the lamb sandwich at one of the booths outdoors. Oh yeah, the Greek beer is pretty good too.
It should be a beautiful weekend for the festival. It's at the Greek Orthodox Church on Lincoln next to the Mormon Temple.
