Nish Kumar joins Richard Ayoade for a potter round Porto, Portugal's second city. They start their trip with a welcome tipple of the city's eponymous fortified wine. To get their bearings, Richard and Nish hire electric scooters. They refuel with Porto's favourite sandwich, the meaty Francesinha; take on a 5D cinema experience; and are pushed to the boundaries of physical endurance as they climb the Arr?íbida bridge. Their brave ascent is rewarded with great views of the city and the ocean. At a local church, Nish makes a confession. Absolved, the duo indulge in a selection of local pastries with a cake connoisseur, and test out artisanal soap in a genre-defining hand washing sequence.
