I'm used to shopping for wines in either a liquor store or a grocery store, where you walk past shelves packed with bottles, with little distinguishing one from another. So I was delighted to find Best Cellars, north of Dupont Circle on Connecticut. They probably have less the 50 wines for sale at any given time, but they have them displayed artfully, with excellent descriptions that allow you to compare a wine to the wine next to it. The staff is knowledgeable / helpful, the atmosphere is great, and the selection more than covers your needs. And all at an amazingly affordable price.
