investment into a Staten Island Ferry with fellow “Saturday Night Live” cast member Colin Jost, Pete Davidson is now also dipping his hands into New York’s bar scene. Davidson, 28, joins a long list of celebrity investors behind the 19th century townhouse-turned-bar, including music producer Mark Ronson and actors Nicholas Braun, Justin Theroux and Jason Sudeikis. Dubbed Pebble Bar, the new multilevel watering hole with a secret entrance via Rockefeller Center replaces a longtime pub so frequented by “SNL” cast members they often referred to it as “Studio 1-H.” But Matt Kliegman, who is a partner investor in the space, told The Post he wanted the vibe to feel “residential” and “intimate,” despite its ritzy features and high-profile backers.
