The iconic Carnegie Deli has reopened downtown for a week, thanks to Amazon’s hit series “The Marvelous Mrs. Maisel.”

The pop-up is in Nolita, rather than the original institution’s Midtown location on Seventh Avenue and 55th Street, which closed in 2016 after four decades.

Mimicking the world of the hit period comedy, the downtown pop-up looks like a 1950s deli, and items are priced appropriately, with sandwiches, named after characters from the show, going for 99 cents. (The former menu was known for behemoth sandwiches that shared names with stars, such as the 4-inch-thick pastrami-and-corned-beef Woody, named after director Woody Allen.)

All funds and tips go to the Lower Eastside Girls Club.

There are 6,000 people on the waitlist to get into the place, which is running through Saturday.

But Joshua Greenberg, the executive producer of the pop-up, told “Page Six TV” that the hot spot could keep going if New Yorkers show up.

According to Vogue.com, “waitresses wear knee-length dresses with buttons, capped sleeves and aprons, and they greet customers with terms of endearment.”

The spot’s signature sandwich, the Maisel, is for “women who eat, not ladies who lunch.”
