I was a server there for a long while, and I've had many compliments about that cake. Having tried it a number of times, I can say there is a strong whiskey taste, if you don't like whiskey - you'll for sure notice it more. It does bring out a lovely flavor in the chocolate, as well.
It's no longer served at dinner, and there is talk of getting rid of it at lunch as well - the menu change is on March 14, so you'll know then.
