Chez Maman looks like a great place. Or is it places? It is not clear by their site if what seems to be two other Chez Maman locations are open or not. Anyone got the skinny? Any one better than the other? I hear Portrero Hills is the one with the raves, but what about the one listed on Union Street? Going to SFO on Wednesday. Hope someone can set me straight before I leave. Thanks.
