One of the most beautiful Chinoiserie wallpapers is Scalamadre's Shanghai. Based on period paintings of Cathay, its look is classic, traditional, elegant, old money. This large scale seven color Chinoiserie toile is very dramatic, eliminating the need for any art on the walls whatsoever.
Shanghai would be my first choice for an entryway, as shown below in the apartment of Merrill Hanley. This apartment was designed by Keith Irvine and featured in Domino Magazine.
Below is the dining room of Meg Braff wallpapered in Scalamandre Shanghai. The wonderful Chinese red paint she used is Farrow & Ball Blazer. The brass sunburst mirror, Chinese Chippendale chairs, and beaded chandelier are modern pieces, giving the room a youthful and preppy feel. Pictures are from House Beautiful.
