Can you imagine being a young American designer with a vision to go from selling ties in New York to becoming one of the most well respected fashion houses in the world? That was Ralph Lauren’s vision and now that vision includes going into the restaurant business. The American fashion label has opened its first restaurant in New York’s Fifth Avenue flagship store on the second floor called the Polo Bar. The restaurant is warm and inviting and doesn’t look anything like the kind of restaurant Manhattan has seen for many generations. That suits Mr. Lauren just fine. “I’m about longevity, I’m about timeless,” Mr. Lauren said, sipping a cup of his own brand of coffee. “It was not my idea to be trendy. I don’t want to be the hot restaurant. I want to be the restaurant you want to go to twice a week.” Patrons will be able to stop in and grab a burger, a sandwich a cup of coffee or Polo Bar mugs and T-Shirts.
