In addition to Folsom Street Fair and the hugely popular Eat Real Fest in Oakland this weekend, there is also another fest happening on this side of the Bay that will be chock full of dolmas, moussaka, and hopefully fried cheese. It's SF's only annual Greek Festival at the Greek Orthodox Cathedral of the Annunciation (245 Valencia Street), and it runs all this weekend, September 21, 22, and 23, from noon to 10 p.m. (8 p.m. on Sunday).
Click here for a postcard that gets one person in free, otherwise it's $5 to get in. And there will be entertainment that will be very different from what you'll find a few blocks away at Folsom. See more info here.
