Make no bones about it, this Cantonese canteen is no-frills but it's what you'd find shoved down a steamy side street off Mong Kok, Kowloon-way. So are the flavours: load up on (roast pork), roast duck, roast goose or steamed bream with ginger and spring onion and sink a Tsingtao (totally wrong side of China, but it's still China's best beer).
