Hamburger Font BF is an endearing tribute to the lettering style of a logo, long retired, from a certain chain of fast food restaurants.

It joins that fraternity of heavy, fat, round, and pleasingly-plump faces such as Cooper Black and Frankfurter; and it serves as a delightful alternative to such.
It’s suitable for a wide variety of uses from children’s media projects, to headlines where a cool, informal appearance is desired.
