Top 10 London Restaurants with a View
"Following on from the Duck and Waffle, and also in the Heron Tower but this time on the 38th and 39th floor, is Sushisamba. This restaurant offers a unique blend of Japanese, Brazilian, and Peruvian cuisine. There are delicious sushi and sashimi dishes to enjoy and again, splendid views of the Gherkin."
