There are lots of museums in Paris but I'd say this is definitely worth a visit if you are only doing 1. The entry fee is pretty reasonable relative to other European galleries. The building itself, which has recently been spruced up, is super impressive and almost worth the trip itself. The art though is the obvious attraction. I am certainly no art expert but I was very impressed with the Impressionist rooms. I'd be surprised if most people don't recognise several of the pictures on display. Lots of famous artists' - Renoir, Monet, Manet, Sisley, Van Gogh - work on view. A good couple of hours spent here.
