Corridor 44 does fans of sparkling wine a service by cracking some truly fine bottles of the bubbly and pouring it by the glass. Perrier Jouët Grand Brut, Moët & Chandon White Star, even Veuve Clicquot Yellow Label — the best champagne you're going to get before you start paying as much for your booze as your entree. And now, with a menu restructuring courtesy of consulting chef Troy Guard, you can pair your champagne, prosecco or plain brut with tastes of American caviar (at $100 an ounce), cucumber and wasabi oyster shooters, tempura lobster salad or even chocolate fondue.
