The rather dingy Lin Heung Tea House has been offering dim sum from trolleys since the 1920s and is always packed to the rafters with hungry diners. You’ll find it up on the first floor, past the pastry shop.

No one will seat you, so you’ll have to stand vigil with the others hovering about waiting for a seat; most likely you’ll share a table. Unlike most restaurants nowadays, dim sum is still served from trolleys, and since there’s no English menu you’ll have to take a peek inside the various baskets. The house specialty is dai bao (fluffy dough filled with chicken, dried mushroom and salted yolk), but good luck trying to nab one, as only 100 or so are baked daily and they’re gone almost as soon as they come out of the kitchen. However, there are plenty of other options, except when trolleys can’t seem to get out of the kitchen fast enough and hungry diners crowd around the carts. Then it’s a free-for-all, and not for the faint of heart.
