Going to the grocery store could be worth $20,000 for one chef in each episode of this competition series; four chefs compete in three elimination challenges testing their culinary skills as they make their way through the store's aisles; each challenge features a theme -- such as using only items from frozen foods -- and is judged by a rotating list of guest judges who determine which contestant is eliminated; the chef who makes it through all three challenges then has two minutes to go through the aisles collecting items on a shopping list. Each item on the list is worth $2,000 and if the chef gets every item, the $20,000 grand prize is awarded; popular Food Network personality Guy Fieri hosts the competition.
