No bad sauce between Bay View pizzeria and Barstool Sports founder Dave Portnoy

MILWAUKEE (CBS 58) -- A popular pizzeria in Bay View is in the spotlight after a less than glowing review on social media.

Monday, Jan 30, Barstool Sports founder Dave Portnoy stopped by Classic Slice, but it was closed for its employee party.

Portnoy took his frustration out on the restaurant on his social media channels.

The General Manager of the pizzeria, Jason Zbichroski, said he was surprised when Portnoy appeared on his restaurant's steps.

"I was standing right there (gestures to cash register), and I looked, and was like, that looks like Portnoy, let me go see," said Zbichroski.

Zbichroski offered Portnoy cookies and beer for the inconvenience of the restaurant being closed, but he could not offer him pizza.

Portnoy accepted the cookies and rated them a 4.7 out of 10.

The pizzeria has been open for more than 15 years and has customers from all over.

"This is the first place I had decent pizza in America," said Dirk Cook.

Cook, originally from Scotland, has lived in Milwaukee for 13 years, and for the better half of a decade he only gets his za' from one spot, Classic Slice.

Cook doesn’t proclaim to be a food critic, just a lover of pizza.

CBS 58 was curious about Cook's thoughts on what controversial influencer Dave Portnoy had to say about his second home, so we showed him the viral video.

"(laughs) He could have called ahead," said Cook.

And while customers, like Cook, were seeing the video for the first time, others said they have been following Portnoy since the beginning.

"I saw the video and I thought, Classic Slice, I've never heard of it, and I'm like, Dave went there I probably want to try it out," said Mike Madia, a Milwaukee resident and first-time customer of Classic Slice.

Zbichroski said there is no "bad sauce" between him and the influencer, and he's actually a fan.

Zbichroski said he's looking to keep Classic Slice a hidden gem.

"I'd rather the local people be able to access this place like they do every day. It’s a neighborhood pizzeria," said Zbichroski.

Portnoy also made stops at several other pizzerias throughout Milwaukee County.
