|I did manage to see a notecard that said "New York Cheesecake" flavor.|
My original intent was the show you actual Georgetown Cupcakes and report back on how good it was. However judging by the line it was probably good, if not popular.
For inquiring minds, Georgetown Cupcakes is a DC-based cupcake shop that opened up a New York location in SoHo. If you like lines then head to 111 Mercer Street (between Spring and Prince Street) and report back.
