Colorization looks weird in this one. Also, the cars are not nearly as interesting as they would become just a few years later; by the mid/late '50s, there was a lot more variety and more sports cars, etc.
DuPar's is still around at the Original Farmers Market on 3rd and Fairfax, it is where Harry Bosch is eating w his ex-wife when she gets whacked. All of the other locations are sadly gone.
