Pennethorne's Cafe Bar | Visit London
Nestled within the New Wing of culture venue Somerset House, this all-day café is themed on the Grand Tour experience.
Pulling together dishes from popular stop-offs on the arts-focused route taken by the upper classes in the 19th century, you can expect to find Italian and French classics with a modern English twist; as well as speciality breads.
