Arby's has a new breakfast menu only available at one location - here's the one item that needs to go national

The recently opened Arby's in New York City isn't just the first to open in Manhattan in almost a decade. It is also the only location in the world testing a new, revamped breakfast menu.

While about 200 Arby's restaurants serve breakfast, only at the New York City location can customers purchase options such as a brisket biscuit, flatbread breakfast sandwiches, and breakfast sliders.

If the test goes well, Arby's may begin to serve some items at other Arby's locations that offer breakfast, the company told Business Insider.

To determine which of Arby's new breakfast offerings should go national, Business Insider decided to test the revamped breakfast menu.
