Greetings Hounds of Chow:
For a cool refreshing drink try a chocolixir at Godiva Chocolatier (I got it at Broadway and 41st). It's like a Frappucino, but made with far superior ingredients. And you can take tiny pieces of Godiva chocolate chunks even after it is blended. They were giving out free samples, and then later I went and bought one.
Price is $4.50.
