Champagne Garden 2015

Trust the Hotel Chinzanso to supply a classier alternative to Tokyo's beer garden booze-ups. The elegant Mejiro hideaway is putting its rooftop Serenity Garden to good use for this summer-only promotion, where ¥7,900 gets you two hours and four varieties of free-flowing champagne – that's Laurent-Perrier, Moët & Chandon, Nicolas Feuillatte and Mumm for all you connoisseurs. The price also includes cocktails, beer and a selection of nibbles, though you'll need to book in advance to take advantage of the offer. And if all that still doesn't sound satisfactory, you can go for the ¥10,000 package and unlimited amounts of Moët Ice Impérial, 'the world's first champagne created for hot days'. Yeah, right.
