The Oval Restaurant at The Wellesley London

This smart-looking restaurant is located at the very swanky, five-star hotel, The Wellesley, on Knightsbridge. There's an opulent art deco look to the dining room, with a very bling chandelier providing the centrepiece. 

The menu is Italian, though influences from around the world feature. Expect, then, dishes such as risotto with prawns, white asparagus and lobster bottarga, and beef tartare with shaved Norcia black truffle and hazelnuts alongside soy-glazed octopus with pearl onions, saffron potatoes and corn sauce, and dover sole meunière with grilled asparagus and Mediterranean sauce. 

Expect a wine list you can splash out on, too. The dress code is 'elegant'.
