Riddling Widow is a tiny champagne bar in a basement in Greenwich Village. Although if that sounds fancy, you should know that it isn’t. It’s extremely laid-back, and the service is casual. Think of it as your friend’s 70′s-themed basement where there happens to be an excellent selection of sparkling wines. And if those aren’t your thing, they have the basic red and white varieties as well. Stop by. They might even be playing vinyl.
