This is the most sturdy kind of delicacy in the northern area of Henan, where a lot of meat is put into Puyang Zhuangmo, Anyang Zhuangmo, Henan Zhuangmo
I ate something similar in Jining, Shandong province. It was a more proper place but you can not expect too much tidiness since once you boil the oil, walls and windows get oily everywhere without a remedy. It is very very satisfying to eat especially when one is hungry. You feel the fullness in it.
