Multimillionaire and Barstool Founder Dave Portnoy stopped by two Nassau County staples – Gino’s Pizzeria in Williston Park and da-Angelo Pizzeria & Ristorante in Albertson – to review the spots’ classic cheese slices.

Although the businessman owns a house in Montauk, he often slams Long Island pizza in his YouTube pizza reviews.

“I say Long Island always overrates their pizza,” Portnoy said in his video reviewing Gino’s. “They don’t have great pizza on Long Island. For whatever reason…the memo to make pizza crispy has never translated to Long Island.”

Portnoy reviewed Gino’s and da-Angelo’s in two YouTube videos uploaded to One Bite Pizza Reviews April 26 and April 29 respectively.

During the three-minute reviews, Portnoy was stopped by Long Island customers who asked for selfies and complimented his career multiple times.

The celebrity said he heard there was a rivalry between Gino’s and da-Angelo’s, which are located just down the road from one another on Willis Avenue.

Portnoy reviewed the cheese pizza at Gino’s first. He said the restaurant had a tame atmosphere.

“Couple old-timers working behind the register,” Portnoy said. “Very quiet. Just everyone kind of eating to themselves.”

Portnoy then dug into a slice, which he described as thick, heavy, cheesy and a little greasy.

“It’s exactly what I expect a Long Island pizza to look like,” Portnoy said.

At the end of the review, Portnoy said the slice was “actually pretty good” and had a nice, light crust. He gave Gino’s a 7.4 rating out of 10 for its “wintery football pizza.”

Pete “Tiny” Polumbo, a Gino’s employee, said Portnoy’s visit was totally unannounced and unexpected.

“Everybody’s entitled to their opinion. If they don’t like certain pizza, then they can go where they like,” Polumbo said. “It was nice that [Portnoy] came here…and I appreciate what he does for small businesses.”

Polumbo said he personally loves New York pizza and his favorite pick at Gino’s is a Sicilian slice.

Portnoy stopped by da-Angelo’s next, where he also picked up a cheese pizza. He said da-Angelo’s was busy and loud.

“This place is jammed,” Portnoy said on his way out of the pizzeria. “Full restaurant. Full busy.”

The Barstool founder said da-Angelo’s pizza had a similar Long Island look to it and a very doughy texture.

“It’s chewy. All Long Island pizza is chewy,” Portnoy said.

Efforts to reach da-Angelo’s employees were unavailing.

Portnoy gave da-Angelo’s a 7.3 rating out of 10, meaning Gino’s beat its Willis Avenue competitor by just a tenth of a point, though Polumbo said there isn’t actually a rivalry between the two local businesses.
