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... (more) 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.
