Naturally, we weren't allowed to assemble these ourselves. So we inelegantly gnawed our rapidly deconstructing rolls under the watchful eye of the staff, feeling like lumpen hicks.
The duck reappeared as a stir-fried course - which is correct - but not as a broth which would complete the traditional trio. It was ordinary. Cubes of pork belly combined the tooth-unfriendly qualities of crackling with deeply chewy layers of more fat.
These came with salad cream and a mix of sugar and salt; dead authentic, for sure, but it should have come with a government health warning.
We went back for dim sum. This was a marginally better meal from a genuinely intriguing menu: pillowy pan-fried buns stuffed with savoury lamb; sticks of venison satay; gnarly but lipsmacking little ribs in black bean sauce; crab roe siu mai (or shu mai); dried scallop and glutinous rice in lotus leaves; my favourite char sui pastries.
But quality was still wobbly: delicate lobster dumplings self-destructed on contact with the chopsticks; siu mai were tough, wrinkly and padded with frozen-tasting prawn; the rice was less glutinous than soggy, the venison tough.
This new venture may come across as a massive raspberry pointed meaningfully in the direction of the parvenus. But it's got a long way to go before the food matches the ethereal beauty of the Yau scallop shu mai.
The service may be Club class but the food is more like economy.
