On their way to Las Vegas for a convention, Fran discovers that his cousin Sal, being the (ahem) "financially conscious" type, has booked them on a connecting flight through St. Louis. The only problem is that it is an 8-hour layover. But, there is a method to Sal's madness. He has mapped out iconic eateries in St. Louis to try out, starting with Tiffany's Diner on Rt. 66. This place has been serving up "Slingers" - a traditional St. Louis breakfast - since 1960. Then, the guys head over to Russell's on Macklind to try a unique spin on another classic on the Gateway City - Gooey Butter Cake. No layover is complete without discovering the local pizza scene, so Sal and Fran head to Frank & Helen's for a slice or two of their famous St. Louis-style pizza and Toasted Ravioli. Turns out, St. Louis is so delicious these pizza masters might just extend their stay.
