Bizarre Foods focuses on regional cuisine from around the world which is typically perceived by Americans as being disgusting, exotic, or bizarre.

Originally a one-hour documentary titled Bizarre Foods of Asia, repeated showings on the Travel Channel drew consistent, considerable audiences.

In 2009, Zimmern took a break from Bizarre Foods to work on one season of the spin-off Bizarre World.
