Hairy Bikers: Route 66

The third leg of Dave Myers and Si King's trip sees them on the trail of Oklahoma's famous beef. In Oklahoma City, a classic T-bone steak is followed by a visit to the city's Vietnamese community, where they knock up their national dish pho - a broth made of beef or chicken. After checking out El Reno's unique onion burger the duo hook up with a couple of fire crews who like to cook - especially brisket. An organic sweet potato farm inspires Dave and Si to make sweet potato brownies, before they finish this stretch on a cattle ranch with America's most iconic custodian of the land - the cowboy.
