Pay attention as you walk along Wardour Street, adjacent to Leicester Square – it’s easy to miss HK Diner’s narrow frontage. The interior is bigger than you might expect, and staff will hasten you towards any unoccupied booth seating.
The menu covers Chinese standards, such as roast duck (impessively succulent) and various Chinese greens stir-fried with your choice of sauce, but on our last visit we were most struck by the generosity of the seafood (scallops, carved squid) in a noodle dish. Everything was perfectly cooked and the service was gracious, which is reflected in the prices being a little higher than the Wardour Street norm.
The bubble teas (a long list, from mango to iced red bean with coconut milk) are excellent, and, usefully for night owls, the place is open until 4am daily. Note there’s a minimum £6 a head charge.
