It will also offer seasonal arancini (rice balls) which will change on a daily basis.Smaller plates will have the option of including celery, anchovy, green olives, mint and bottarga; or charred, pickled artichokes, young rocket, Parmesan snow.
He said: “I’m thrilled to have Louis on board at Bancone. He’s incredibly passionate about Italian food and produce and comes from a prestigious restaurant background. Italian food — particularly pasta — is enjoying the limelight in London once again and we can’t wait to open on William IV Street and bring you our modern interpretation of the cuisine.”
