Housed in a red-brick Victorian building since 1881, George’s Street Arcade is one of Europe’s oldest purpose-built shopping centres and a treasure trove of the offbeat. Browse stalls selling vintage clothing, secondhand books, records, jewellery and street food beneath the ornate roof. It is a brilliant spot to shelter from a shower and hunt for a one-off keepsake. Go on a Saturday when the arcade is at its liveliest and the food stalls are in full swing.
