That is indeed the Grey Stuff. It's not the Triple Chocolate one, but it is a chocolate cupcake with the grey stuff on top. And it was indeed delicious-we didn't have to ask the dishes!
Cool. We haven't been able to get a dinner ADR at BOG but I do believe we'll have to try for lunch there one day. Only thing is, I would probably want one of the sandwiches but they always look a little dry in the pictures I've seen. I wonder if they'll let me order some extra sour cream or Dijon mayo on the side? Anybody tried that?
