Miyama is a very peaceful Japanese restaurant, with discreet little booths as well as conventional tables. A wide range of dishes is executed effectively here, from very fresh sashimi and sushi through to the grilled teppanyaki and fried tempura choices. Service was extremely courteous. Stick to beer and sake to drink. There are many trendier Japanese restaurants in London, but there is a reason why a mainly Japanese crowd returns year after year to this establishment.
