Over the weekend, the legendary TV personality enjoyed the nice weather while grabbing some grub at Locanda Verde at the Greenwich Hotel.
Letterman hosted his last show in May and has been keeping a low profile since his exit.
In a recent interview with “Sunday Morning," Letterman joked, "I doubt that anybody will ever see me again.”
Though Letterman is retired, it is unlikely that he'll just be sitting at home. He has agreed to travel to India next year to appear on an episode of "Years of Living Dangerously," a National Geographic documentary series, which focuses on climate change.
