Beginning Monday, November 19, 2018, the new Arbynator Sandwich will be available at participating Arby’s locations nationwide for a limited time.

The Arbynator features the brand’s signature thinly sliced roast beef topped with Curly Fries, cheddar sauce, Arby’s sauce and Horsey sauce on a sesame seed bun.

The sandwich, dubbed as the “Most Arby’s Sandwich Ever Made,” will be available in classic, double and half-pound varieties. The double Arbynator features twice the amount of roast beef than the classic, while the half-pound version boasts the most roast beef of the trio.

All three varieties will be available at participating locations from November 19 through December 23, 2018.

The Arbynator first appeared at select test locations in Michigan and Oklahoma back in December 2017.
