The six teams remaining enter the mountains of Pocatello, Idaho. For their Speed Bump challenge, they have to rework their dishes to get rid of all starches on their menus. On day two, they're given their Truck Stop challenge: they have to dig up the potatoes they need at a nearby farm, and they'll need a lot, as the potatoes must be the main ingredient in all menu items. After reaching their sales goal, they race to a vista high above the city, where the first three teams to arrive win a reward, and the team who sold the least over the weekend is eliminated.

Four teams remain as they enter the Twin Cities — Minneapolis and St. Paul. In honor of the Twin Cities, Tyler gives the teams twin Truck Stops. On day one, to honor the Minnesota state fair, the teams must serve all of their menu items on a stick. On day two, the teams head into St. Paul and must make $500 selling SPAM dishes. The first team to make $500 and meet Tyler at the Peace Officers Memorial at the State Capitol building wins a huge reward, and with only four teams left, this reward could save a team from elimination and send them on to the next city.
