A good Champagne bar should be as effervescent as the wine it serves. Some are bright, playful spaces to get giddy with your friends over French fries and Pét-Nat, while others are elegant, moody settings perfect for enjoying caviar and coupes of Dom with your lover. Moreover, some combine irreverence and elegance, such as pairing cloudy California bubbles with briny oysters or indulging in Grand Cru Champagne with tater tots. There are various styles of sparkling wine bars, but the best ones break outdated notions of Champagne as stuffy or elitist, bringing bubbles into the hands and hearts of everyone.
