Jung Song and Dok Kwon, both Korean immigrants, say they're living the American dream.

Their Provo, Utah-based Korean barbeque company, Cupbop, started out of a food truck in 2013. Today, it's a restaurant operation with 36 locations across six U.S. states — and more than 100 locations in Indonesia — that recently brought in $18.7 million in revenue over a 12-month span, the duo said on Monday's episode of ABC's "Shark Tank."
