On Monday evening, New Yorkers huddled across the boroughs to watch the Knicks play the Spurs in Game 3 of the N.B.A. finals. Some celebrities, including Spike Lee and Timothée Chalamet, snagged courtside seats, but downtown in the former Tribeca Grill space, others joined an unexpected group of Knicks fans for the 19th annual Chanel Tribeca Festival Artists Dinner.

Just before tip-off, five big-screen TVs stationed around the room were powered up. Bowls of caramel corn were arranged near napkins with the Chanel logo embroidered in orange and blue. Trays of black-and-white cookies — made instead with orange-and-blue frosting — floated around the room alongside Knicks caps stacked on silver trays.

“We’ve been waiting for this moment,” said the actress Teyana Taylor. “I feel like a kid again.” (The party ended a few hours before the Spurs held on to beat the Knicks, 115-111.)

The Tribeca Festival runs through June 14, and kicked off last week with a premiere of Madonna’s short film “Confessions II,” featuring the first six songs from her upcoming album of the same name. Monday’s dinner honored 10 artists who donated works that are presented to Tribeca Festival winners, including Kiki Smith, Hank Willis Thomas and the twin designers Soull and Dynasty Ogun.
