At any café in Paris, your coffee will likely be served in a Cafés Richard cup.  
What is Cafés Richard you ask? 
They are a company whose fresh roasted beans
are delivered daily to Paris' cafés and restaurants. 

I have several Paris cups and Paris mugs,
but why have I never bought the cup so well-known to Parisians? 
I will be doing so this week if I can buy a single cup or two. 
This is called their Perle Noire Cappuccino Cup and Saucer. 

Perhaps I need the expresso, the black Florio design, the Richard Coffee Cup and Saucer with the logo... My carry-on may be a bit heavy on my return to the US.
