A Chinese friend of ours is visiting from the US and her mom and brother (both also visiting from overseas; they left China years ago) organized a Mid-Autumn Festival dinner for us at Hepingmen Quanjude. I had never been to this location, despite it's being the world's largest duck restaurant (or perhaps because of that) and now I feel like I have not been missing a thing.
First of all, the place really is enormous, with more than 30 dining rooms on four floors. They really churn out the ducks here, too, since during our stay the little carts with the duck on it pushed by the surgical mask-wearing chef never stopped coming out. As one might expect, the quality of the duck in such an industrial venue suffers a lot. The skin was not the least bit crisp, the meat had virtually no flavor, and the prices were stratospheric. The only thing we ordered that we actually liked was a dish of duck liver that was lightly breaded and then sort of fried, but even that I would not rush to order again.
