We got back from Paris yesterday.  We were there for 8 days - not nearly enough time to sample all the confectionary goodies the city has to offer.  Some of the chocolate highlights:

Visiting Michel Chaudun's chocolate shop.  We got to meet the maestro himself.  He's a lovely man - warm, generous and incredibly modest.  We got to sample some of his wonderful pralines and his signature Pavés (little soft pillows of chocolate heaven).

Patisserie Viennoise.  This unpretentious, bustling little restaurant has what many think is the best hot chocolate in Paris (in other words, the world).  It's thick and intense.  It usually comes topped with a mountain of whipped cream, but you can get it without.  They also serve a variety of pastries.  The one shown below is best chocolate mousse cake I've ever tasted.  I would go back to Paris just to eat one these.
