On this week's journey, Luke discovers a chef’s paradise at Vallum Farm, where he meets up with friend David Kennedy and cooks a mouth-watering pork belly. Luke visits the historic, 116 kilometre Hadrian’s Wall, and prepares a meal fit for a Roman emperor. Arriving in Manchester, our UK-trotter pops into celebrity dining hotspot Australasia Restaurant, before exploring one of city's busiest restaurant strips, Curry Mile, and meeting Manchester’s Mr Pieman. Unbeknown to Luke, the iconic piemaker was inspired by his Vietnamese pho to produce the first and now very popular pho pie.
