Twins Sylvia and Sandra go head to head with twins Daniel and David. The sisters are all tradition as they serve up tried and true recipes from their Spanish grandmother. How will it fare against the brothers' innovative take on comfort food? Will the time-honored paellas and croquettes hold up against the inventive peanut butter with bacon and fried mac and cheese? It's double trouble in this ultimate battle of sibling rivalry.

It's corned beef and pastrami time as two teams follow their dreams to create the ultimate deli. Friends Eric and Donna serve up own version of the Reuben Sandwich in their homey restaurant while brother and sister team Zach and Sasha are straight up New York with their brash "Izzy's Deli" concept.

Aspiring restaurateurs take the theme restaurant to a new level as brothers-in-law Rob and Tom open their take on the German beer hall next door to roller derby girls Ann Marie and Carrie's rockin' gastropub. It's weinerschnitzel and currywurst vs. pork sliders and apple slaw in this battle to create an over-the-top diner experience.
