Sorry this is so late folks! There are quite a few things going on this weekend that SFist already gave you a heads-up about, including the Disposable Film Festival, Shop for Japan, and the Artisan Cheese Festival in Petaluma. Yum! Here are some more things happening -- if you feel like leaving your cozy abode on this rainy weekend.

Hellenic Cultural Parade: FuncheapSF informs us of the celebration of the 190th anniversary of Greek independence. Closing the Hellenic Cultural Week on Sunday is the big march in which paraders dress in the clothing of Greek freedom fighters from the early 19th century as well as others reveling in their Greek cultural roots. The parade runs from 5th St. between Market and Folsom and in front of City Hall with a festival featuring dancing, music, and delicious food. We hope it doesn't get rained out...
