Yes, chef!

Over the weekend, fans of “The Bear” were able to get their hands on sandwiches from Mr. Beef, the eatery that inspired the FX on Hulu hit.

Uncle Paulie’s Deli on West 3rd Street in Los Angeles hosted the pop-up over the weekend.

As fans awaited to try Chicago’s renowned Italian beef sandwiches, they spotted a very familiar face helping out.

In a video posted to Los Angeles Bucket List’s TikTok account, eagle-eyed fans spotted actor Jeremy Allen White putting his culinary skills to good use.

Donning a brownish cutoff t-shirt and a baseball hat, White can be seen behind the counter in the kitchen.

Another user on the platform posted a video showing other stars from the series helping with orders.

Chris Zucchero, who is the owner of Mr. Beef, has appeared in the series as well as Uncle Paulie’s Paulie James.

Both men, along with “The Bear” creator Christopher Storer and his sister, culinary producer, Courtney Storer, were in the kitchen to help make sandwiches.

The pop-up has been deemed a success, but it’s not known if it will return.

Season 3 of “The Bear” is streaming now on Hulu.
