Gregg heads to Barcelona, uncovering the city's artistic side in the incredible architecture of Antoni Gaudi, most famous for the Sagrada Familia, a large unfinished Roman Catholic minor basilica. The MasterChef presenter learns about the city's other artistic sons, while doing a self-portrait in the style of Pablo Picasso. He also visits the street festival in the Gracia neighbourhood, which culminates in the breathtaking castellers, or `human towers", and samples the array of back-street tapas restaurants.

The MasterChef judge visits Scotland's capital, where he heads up the Royal Mile to one of the most documented castles in the world, goes underground to see the centuries-old streets that still remain and learns about the tradition of bagpipe playing. He also learns about Scotland's rich larder with one of its finest chefs Tom Kitchin, helping cook up a feast of grouse and langoustines. Gregg finishes his brief jaunt by joining some locals for an early-morning dip in the North Sea.
