Only on the "CBS This Morning" podcast, chef and restauranteur Marcus Samuelsson discusses how he uses food to tell a story. Talking with CBS News' Vladimir Duthiers, Samuelsson shares how his grandmother influenced his passion for cooking and what surprised him and his mother about New York. The host of the new season of "No Passport Required" on PBS, Samuelsson explains the difference between fast food and road food; and why he's built his restaurants to slow the dining experience down.
