How about the charming roast duck restaurant Jin 'an Road?
It's more civilian, the duck is more affordable, the taste is ok, the food is large, and the table for four people is full of three plates, haha. Generally speaking, the benefits are more than enough, but exquisiteness is not good. Moreover, if you don't make a reservation, you have to go early later, and there may be no seats if you are late. The environment is general, and the service attitude, especially when there are many people, needs to be improved.
