I never did find the Grand Marnier crepes, but I'm told they weren't cheap
They weren't dirt cheap, but not to excessive.
The great thing about them was that they put a generous measure of Grand Marnier on them but also had bottles of the stuff on the counter so you could put extra on them!
At 2am on a cold night you could crimp the paper plate and pour a triple of warming GM down your throat and then the carbs and sugar from the crepe were a godsend.
Greatly missed!
