The new Champagne bar at London’s May Fair Hotel does not pour bubbly by the glass, serve fizzy cocktails, or, for that matter, even have a bar. Dubbed 150 at the May Fair (www.themayfairhotel.co.uk/150), the intimate sunken lounge within the hotel’s May Fair Bar offers vintage Champagne by the magnum (as well as magnums of Belvedere vodka). The centerpiece of 150 is a floor-to-ceiling glass refrigerator that chills the 1.5-liter bottles of Ruinart, Krug, Moët & Chandon, and other labels. The two four-course canapé menus by the May Fair’s chef, Silvena Rowe, pair specifically with Dom Pérignon’s Vin­tage 2000 (the menu includes lobster with tropical salsa and cumin-flavored crème fraîche) and Vintage Rosé 1998 (pomegranate-glazed foie gras).
