Here is a nice trompe l'Oeil mural in Montpellier, France.
Trompe l'oeil (French meaning 'deceive the eye') is an art technique in which the painting produces an optical illusion and the depicted objects appear real and three dimensional.
Notice that expect for the waitress, all other persons and objects in the background are NOT real and are actually part of the large mural. Even the large glass window is not real.
To fully appreciate the art work open it in larger Google Street View.
