If a glass of fizz is your thing, stepping into Bubble Lounge may well make you think you have died and entered champagne heaven. Like its sister venue in New York, this place is, as the name implies, all about the bubbles, stocking over 300 different labels, some 30 by the glass alone (though if you're accompanying a champagne enthusiast and aren't a fan yourself, never fear: there are plenty of still wines, scotches and cognacs on offer, you won't go thirsty). There's an extensive cocktail list (both fizz and non-fizz) we're fans of the Champagne Mojito, or the Cashmere and Silk (Grey Goose la Poire and St. Germain, topped with Prosecco); for the non-bubbles crowd, try the Rasmapolitan (Stoli Razz, Combier, cranberry, and lime juice) or the Safari (Starr African rum, ginger liqueur, lime, peach nectar and peach). Food tends towards the small plates, featuring charcuterie and artisanal cheese, or finger food such as spring rolls, though there's heartier fare on offer, too, to soak up the booze (burgers and the like) and a tempting selection of desserts. Ifif you're not sick of the fizz by the time you order your dessert, try the Champagne Chocolate Truffle with Grand Marnier. It's an undeniably feminine space, popular for hen parties, showers and girls' nights out (if you're still mourning the passing of Sex and The City, you'll really like it), but why should that be a bad thing? There's also a sumptuous VIP room - the Krug Room, an intimate setting where indulgence is accompanied by fine delicacies like oysters and caviar. A light-headed sea of bubbles could lead you anywhere from here.
