Cafes don’t get a whole lot smaller than Genki in St Agnes, which is to all intents and purposes a painted hut with a few cosily packed tables, occupied on my visit by Finisterre-clad surfers. But this particular little beach hut has a few other strings to its bow: a sweet Zen-style cafe garden inspired by the owners’ time in Japan, free wifi, and a serious smoothie menu.

Smoothies are often the most expensively disappointing thing on cafe menus in this country – insubstantial and never cold enough. But something told me to try my luck on the Mavericks Mocha Smoothie (£3.50), which contains banana, cocoa, peanut butter and espresso. It was stupendous – thick, ice-cold, filling, sweet not sickly. Crap cafes of Cornwall, take note.
