Fast-casual restaurant Portillo's made its IPO debut on the Nasdaq on Thursday, and CEO and President Michael Osanloo joined Cheddar's "Closing Bell" to go into the decision behind taking the company public. He also discussed pushing through the pandemic when the restaurant industry was struggling to sustain itself. "We've never closed a restaurant in 58 years," Osanloo noted. "Every one of our restaurants is profitable, and we're thrilled to keep building off of that incredibly strong foundation."
