BurgerFi is an international fast food restaurant chain focused on hamburgers, french fries, hot dogs, and custard. The chain is rather unique in the fact that they brand their burgers with their logo before serving them to customers. — Wikipedia

The logo appears to use Steve Jackaman’s revival of Steelplate Gothic, originally from 1918. A modified version with the drop shadow removed also seems to exist, as well as a 3D version. On the website and on signs, it’s accompanied by the Brandon series by Hannes von Döhren.
