With the ultimate summer getaway worth $25,000 on the line, Chef Antonia Lofaso presents the final three chefs with their most intense challenges yet. The chefs will have to set up their own beach shack where they'll serve the judges and the public their best shack snack. Then, the last two chefs standing create a signature coast dinner -- entrée and dessert -- using ingredients from their dream destination. They'll be presenting their final dish to one of the most iconic chefs in the world, Guy Fieri, to prove their coast has the best beach food and claim the Best of the Beach title.

Chef Antonia Lofaso is back on the beach for a day of roughing it! In the first challenge, mentors Eric Adjepong and Brian Malarkey are off on a fishing boat catching seafood, while the remaining chefs must pack their backpacks with all food, cookware and utensils they'll need to make a rustic seafood feast at their beach campsite. In the second challenge, two chefs from the same coast will fight for their survival using only one open flame in the sand. In the end, one chef will be eliminated, and their beach adventure will come to an end.
