A Hawaiian cafe in Shanghai sounds like a recipe for disaster: pasty fuwuyuans in cellophane hula skirts bearing tiki head mugs, and cloying, pineapple-drenched dishes etc. But the Japan-based WK Hawaii is quite the opposite with a solemn, speakeasy vibe, and a menu that reads like the International House of Pancakes,’ plus a couple Hawaiian options. It’s almost too opposite. You actually end up wishing someone would throw on a plastic leigh for old time’s sake. Fortunately, all is forgiven when you a bite into one of their scrumptious flapjacks.
