Watch Shake Shack's Creators Talk New Fries on CNBC

Restaurateur Danny Meyer and Shake Shack CEO Randy Garutti stopped by the New York Stock Exchange today to chat with Closing Bell's Maria Bartiromo about Shake Shack's 29 international locations (and counting).

It's a spirited conversation about changing fast-food culture and why Shake Shack will probably never be publicly traded, but perhaps most crucially, the duo touch on the Shack's controversial new hand-cut fries, which were unleashed earlier this week at the Shack's Upper East Side location. Says Garutti: "It has caused the most fun, incredible debate this week. We're thrilled about it. It's fresher, it's better, it tastes like a potato. You'll see all the Shake Shacks, over time, convert. We're pretty proud of it." Go, watch:
