Canary House

You're in Canary Wharf territory, which usually means chain restaurants and expense-account blandness. Canary House breaks that mould entirely. Tucked into the Dorsett Hotel on Marsh Wall, this is a proper Cantonese spot that takes itself seriously—the kind of place where your dim sum arrives from the kitchen actually hot, and the roasted ducks hanging in the window aren't just theatre. The room itself is sleek without being pretentious, and the fact it's attached to a hotel means the operation runs like clockwork. Service is attentive without hovering. Come for lunch if you want the full dim sum trolley experience, but dinner's where the real cooking shines through.
