Da Silvano, the celebrity/media-infested hotspot in Greenwich Village, is now selling orange t-shirts. (Ugly orange t-shirts, our spy reports.) This is, of course, another sign of the increasing Olive-Garden-ness of the restaurant. Other evidence: the inexplicable balsamic vinegar in a spray bottle and the sinking feeling that at any second the waiters are going to gather around the next table and launch a hand-clapping back-slapping rendition of "Happy Birthday"or "Bon Compleanno," as it were. [Ed.the old but fairly reliable "Happy Birthday" index of restaurant quality.] If I didn't like the foodits saving [overpriced] graceI'd already be referring to it as "Carmine's on 6th."
