Having just opened their first restaurant, RPM Italian, earlier this year, Giuliana and Bill Rancic are taking great care to make sure their forray into the food service industry goes off without a hitch.

On Tuesday's episode of their STYLE reality series Giuliana & Bill, the expectant parents -- along with Giuliana's Mama DePandi -- assess the goings on in the kitchen of their Chicago eatery.

Chatting with Chef Doug Psaltis, Giuliana seeks her mother's input on the menu items. "Getting Mama DePandi's stamp of approval on the pasta means the world!" Giuliana beams. Confirms Bill: "I never doubted Chef Doug for a minute!"

Later, Mama DePandi speaks her mind on one of the other items: Giuliana's namesake Italian salad. "[Does it have] only one leaf?" her mother quips in front of the restaurant's co-owners and her daughter and son-in-law. "Normally she drinks and [doesn't] eat."

Take a guided tour of RPM Italian with the Rancics in the clip above before Giuliana & Bill airs Tuesday at 8 p.m. (EST) on STYLE.
