Mad for matcha? You'll love the beer garden at Ochanomizu's informatively named Green Tea Restaurant 1899, where ¥3,500 (¥3,000 if you book online) gets you two hours of all-you-can-drink suds with a twist. The available varieties include 'standard' green tea beer, green tea dark beer, hojicha dark beer, 'Japanese black tea' beers in both regular and dark varieties, and non-alcoholic green tea beer – don't ask us about the taste – plus more familiar options like Premium Malts and Asahi Kuronama. You'll need to pay extra for the grub, but it just might be worth it to fork out for offerings such as matcha- and hojicha-flavoured French fries and matcha croquettes. No tempest in a teacup, this one.
