See, one thing about this show is that, while it makes the city an important character, the actual locations can't always appreciate the personalized credit that comes with the screentime. When you've got 14 year olds carousing about the New York nightlife scene without too much conflict or legal controversy, a club wouldn't be so brash as to openly advertise such laissez-faire door policies, right? Nobody wants to glorify such illegal behavior at their establishment, right? RIGHT?
Well, it appears Marquee isn't too concerned about being recognized as an illicit post-tween hangout, as the big I-Banker statutory make-out/Truth or Dare swindle went down there within its once exclusive walls. It's some sort of a relief that they couldn't find an actual restaurant to play the role of the despicably pretentious, stuffy $70 dollar entree joint, so they take a more anonymous approach and sit Serena and Dan in a more unrecognizable banquet hall. (Perhaps they should have checked with this guy first?) The episode bids goodnight with one final wide shot of a cobblestoned Me-Pa district, a gleaming beacon of New York nightlife absurdity. Point taken.
