Here’s a fabulous place to have breakfast, lunch, dinner, afternoon tea, champagne, cocktails, whatever:  it’s open 7 days a week from 8 am to 2 am, it’s stunning, reasonably priced, and it overlooks the courtyard of the Louvre.  Both Parisians and tourists come here, so it’s a nice mix.   Classy, or as the French say, “La classe !”
