Patxi's recipe is pretty close to Zachary's. Apparently the proprietors actually went back and 'interned' at a few of the most famous pie joints the Windy City... however, they're using vegan butter instead of lard to line the pan [the traditional way], which is a big plus for us vegetarians.

One almost feels sorry for Zachary's since you know that it's gonna cut into their revenue, until you consider that-

A) they've likely had the capital to expand into the city for some time now, so fuck 'em and their East Bay elitism; and

B) they actually take plastic money, something which always boggled the mind about Zachary's and their profitability. You'd think the Rockridge location had some secret deal w/ the BoFA ATM pimps next door at Albertson's...

Conclusion? This place has my endorsement. It's lacking the ambience of Little Star (although they've become the loudest restaurant in SF!), but the servers are cool, they serve Hoegaarten draft, I have yet to hear any Kenny G on their stereo... and oh yeah - the pizza's good!
