After a particularly debaucherous night board a Mexican Bus -- a birthday party that took your editor from the Castro to the Marina and back again, a fete of which we recall very little -- we hightailed it back out to the Marina on Sunday morning for a press feast at the Presidio Social Club.

PSC, if you recall, is on federal land and can still legally serve foie gras. (This lady knows what we're talking about!) And while we didn't have any illicit fattened duck liver that morning, we enjoyed one of the best brunches we had in a long time.

Also of note, Presidio Social Club is also a choice spot for brunch with the family. We spotted piles -- piles! -- of children at tables behaving like perfect young ladies and gentlemen. Normally, that would jar the average single San Franciscan into sobreity. But it was a pleasant accompaniment in between bloody marys and wry conversation.

Presidio Social Club: 563 Ruger (at Lyon), S.F.; 415-885-1888
