The MTA now has a sandwich as bold, fragrant, and thrilling as a ride on the subway.

In honor of the subway system’s 118th birthday, two of New York's most well-known sandwich shops have teamed up to make the 1904 signature sub. The sandwich — which was delicious — is a limited edition collaboration between Katz's Delicatessen and Alidoro.

It’s made with a pile of Katz's pastrami, which is topped with a bed of spicy Calabrian pepper-Dijon slaw and a dab of gooey garlic confit and then covered in aged provolone cheese. The sandwich is served on a sourdough rye baguette.

MTA Chairman Janno Lieber chowed down two samples at the Moynihan Train Hall on Thursday and proclaimed them delicious. Unlike another MTA chairman, Joe Lhota, who once considered banning food on the subways, Lieber approved of eating the sandwich on the subway – respectfully.

MTA Chairman Janno Lieber took a relaxed stance on eating aboard the subways after taking a bite of the MTA's 1904 sandwich.

“This is some fabulous garlic confit, but it's less fabulous if it ends up on the business suit or the jacket of the person next to you,” Lieber said. “People are in a hurry, kids have to get to school, people sometimes have to eat in transit, so I’ve never been of those that says ban food. But I do think everyone has to be respectful of those next to them.”

Alidoro’s CEO Jon Streep called the sandwich “f---ing awesome,” adding that exhaustive “R&D” went into its creation.

The sandwich costs $14 and is available through October at four Alidoro locations, not including the original Sullivan Street location (which is regrettably closest to the WNYC/Gothamist newsroom).
