The Downsizing star, 48, and the SNL producer, 38, were joined by other cast members and producers of the NBC show in NYC on Tuesday, December 11.
As for their outings, Matt wore jeans and a dark overcoat, while Lindsay opted for a black dress and tights paired with ankle boots and a patterned jacket.
The pair's dinner comes less than four months after multiple sources confirmed that Ben and Lindsay, who made their relationship public in July 2017, had split after one year of dating.
Shortly after the former couple's break up, in August, the Batman star checked into rehab, later completing a 40-day treatment program for alcohol addiction following an altercation with ex-wife Jennifer Garner and a sober coach.
Matt, on the other hand, "continues to support" Ben, with whom he received an Oscar Award for their film Good Will Hunting in 1997.
A source exclusively told Us Weekly in September, "He’ll always be there for Ben whenever he needs him".
