Season four starts in Los Angeles, under the Hollywood sign, where host and chef Tyler Florence greets the eight teams fighting for their chance to win the grand prize of $50,000 and their own food truck! For the first challenge, the teams must go high class, selling one signature dish in Beverly Hills, Calif., but that dish must be sold for at least $20. The second challenge takes place in San Francisco, where they teams can only sell a NEW signature dish. The team to sell the least amount with their two signature dishes is sent home.
The seven remaining teams head to Portland, Ore., where they're challenged to make the most with what they've got: In their first Speed Bump, they have to go the entire first day without restocking their supplies. On day two, they're given geoduck, which must be the main ingredient in all menu items. After selling $200 with their geoduck menus, they race to a local lumber mill, for a chance to win a reward, which might be enough to save them from this week's elimination.
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.
The five remaining teams meet Tyler Florence at Mt. Rushmore, where they're given their Seed Money, before heading out to shop in Rapid City, S.D. How will they manage when their follow car is taken during the Speed Bump? On day two, they meet at the Cheyenne River Ranch, where they find a side of bison, which they must butcher for use in all their menu items. After selling $1,000 worth of their bison menu, they rush to be one of the first three teams to meet Tyler and win an award, and the losing team is eliminated at the Crazy Horse Monument.
Four teams remain as they enter the Twin Cities -- Minneapolis and St. Paul. As Minneapolis is known for their state fair food, all menu items sold in this city must be served on a stick. They head to St. Paul for day two, the birthplace of Spam, which is their main ingredient for all menu items on this day. The first two teams to make $500 and meet Tyler at the Spam Museum will win a reward: with only four teams left, could this reward save a team from elimination and send them to the finale?
In Chicago, Tyler starts the finalists off on their 800-mile final trek with a Chicago-style pizza challenge judged by Mayor Rahm Emanuel. After the mayor chooses the winner, the teams get ready to sell all day in Chicago when they're given their speed bump: every time Tyler calls, they'll have to move a mile away from their current location. On day two, the teams must use another famed Chicago food in all their dishes - hot dogs. Once the teams make $500, they race to Mike Ditka's restaurant, where the first team to arrive will get a five hour head start to the next city, while the slackers are on dish washing duty.
With their eyes on the grand prize, the final teams are sent all over the East Coast in this last leg of The Great Food Truck Race. After a stop in Annapolis, Md., the teams meet Tyler at a Chesapeake Bay wharf where they haul the crab that will become part of an original crab dish, and maybe the most important crab dish they've ever cooked, as the team with the best dish wins a potentially game changing $1,000 prize. After a surprise elimination, the final two teams are sent packing and selling to the Virginia suburbs and to Washington, where the final two meet Tyler in front of the Lincoln Memorial where they find out who will ride off in their new food truck, $50,000 richer.
