Red Snapper

The Red Snapper is “A Bloody Mary with an inferiority complex,” according to Serena. Apparently it’s even simpler than that — the drink S’s new friend insisted she just had to try at the only bar in town that has them? It’s just a Bloody Mary, full stop.

Which doesn’t necessarily mean that S was subject to a sub-par boozing experience. The King Cole Bar in the St. Regis Hotel actually introduced the Bloody Mary to the United States in the ‘30s. They call it the Red Snapper because Bloody Mary was originally considered too scandalous a name for delicate American ears.

Goodbye, Columbia

The episode title, “Goodbye Columbia,” is a pun on Goodbye Columbus, the title of Philip Roth’s first published book of short stories. It couldn’t be farther than a Gossip Girl milieu — Roth’s stories take place in working class and lower middle class Jewish homes, and the title novella takes place in (gasp!) Newark, New Jersey. Blair would faint.

Matteo

Nate has brand-new Matteo sheets for his tryst with Juliet, which we’re guessing isn’t a courtesy he afforded his parade of skanks this summer — a simple flat sheet set can run $245. We bet the secretly poor Juliet will wait till Nate’s asleep and then pawn them.
