"Walking through Clap’s dark wood-filled space, the view of Harrods impresses from one side, and sushi chefs expertly mince salmon from the other. And the sky-high prices on the a la carte menu at this Japanese Knightsbridge restaurant make the weekday lunch deal taste even sweeter. You get two starters (choose between our favourites like the salmon crispy rice and shrimp tempura rolls) and a main (yes, the black cod is on there)." - jake missing, sinead cranna, rianne shlebak
