Avenida da Liberdade (Avenue of Liberty) is the sort of Regent Street or 5th Avenue of Lisbon. It’s famous for being one of the most expensive shopping streets in Lisbon. It starts at the Marquis of Pombal Square and ends at Restauradores Square (which marks the entrance to Baixa) - so if you have strong legs and a penchant for window (or real) shopping - take a walk down this famous street. There is art and beautiful tiled pavements to keep it interesting as you walk.
