Any fan of Stephen Chow should recognise the above dish – spam with fried eggs on rice – from the actor’s classic Hong Kong film God of Cookery. Ma Sa Restaurant, an old-school cha chaan teng in Sheung Wan, rose to fame as a result of taking this particular dish to the next level, loading it with three eggs rather than the standard two. The runny, creamy egg yolk spreads all over the steaming-hot rice like a finger-licking sauce, the flavour enhanced by a dash of soy sauce. Not a fan of spam? Cha siu is actually the norm, but ham is another equally popular choice of meaty topping. Expect some riculously long queues if you turn up during lunchtime.
