The Take
Biff Burger earns a 22 Slop Score as a genuine 1950s roto-broiled time capsule that died in 2021. The original flame-broiled beef, sesame buns, and secret 27-spice sauce dunk deliver pre-seed-oil civilization flavor.
Everything after the last St. Petersburg location closed is modern knockoff territory.
The Verdict
Seek the classic Biff burger with extra secret sauce on the side at any surviving original recipe source. Avoid all post-2021 revival spots or mystery-meat specials.
Slop Score 22.

Is Biff Burger healthy?
No. Real beef helps but the closed chain leaves no reliable modern version.

Originals did not. Modern knockoffs may hide them per the scan card warning.
Is the original Biff Burger still operating?
No. The last location in St. Petersburg closed in 2021.
