Tamara Palmer at the Feast has word that "McDonalds-style" burgers with their pinkies up will be featured at Street Food Fridays. Behold: "Hot Buns, run by two ladies rumored to have at least one pedigreed restaurant on their collective resumes, will offer McDonalds-style hamburgers made with organic beef and served with pickles, mustard, ketchup, and (we assume) a pleasingly-soft bun at tonight's edition of 'Street Food Fridays' at Fabric8 (3318 22nd St. at Valencia) from 6-8 PM."
Also, there's something or other about pie being served near Valencia and 19th. However, you'll have to check Feast or SFoodie for more details. Writing about warm fruit makes it difficult to keep our lunch down. (Shudder.)
