Frankie Santoro and Angela Santoro-Castelli grew up in their parents’ restaurant, where they absorbed the importance of etiquette and geniality in the hospitality industry. Taking a cue from patriarch Vince Santoro’s heyday, the gregarious Frankie Santoro scoops up a patron’s children, mixes martinis and shares limoncello shots with equal aplomb these days at Frankie’s Ristorante in Tinley Park.

“[He and dad] are both charming and personable, out and about. I like to be behind the scenes [like our mom] making everything happen,” said Santoro-Castelli, Frankie’s Ristorante general manager and events coordinator. “We all compliment each other.”The elder Santoros were born in Italy and moved to the United States as teenagers. The couple, who didn’t speak English, opened Frankie’s Beef & Pasta in Oak Lawn in 1988. It was there that the younger Santoros would be driven to in a Frankie’s Beef van after school.
