[DC/Batman] What is Gotham City's signature food?

Every major city in the US is known for a signature food, or cuisine-- in some cases, multiple foods and cuisines. Philadelphia has its cheesesteak, Minneapolis has the Juicy Lucy, Chicago has the deep dish pizza, Italian roast beef sandwich, and its signature hot dog; Los Angeles has Mexican and Korean, New York City has pizza, Chinese food, Italian food, and Jewish delis; Miami has Cuban food; and so on. What is Gotham City known for? Does it have a signature dish, or ethnic cuisine it is known for?

Since Gotham is supposed to be in New Jersey, probably some variant of Pork Roll.

Probably hard to have a famous signature dish in Gotham, makes you a prime target for Super villain capers.

Because come on there's no way the Joker wouldn't screw over a Gotham institution forever just because that wouldn't name a signature sandwich after him.
