Portillo's spotlights longtime Vienna Beef supplier for hot dogs
Portillo's leans on Vienna Beef as the source of its hot dogs, citing a long-running partnership built around product development and an unusually transparent supply relationship. Vienna Beef introduced its all-beef sausage in 1893, and the supplier continues to provide several million franks annually. In 2024, founder Dick Portillo received Vienna Beef's Legends Award, reflecting the brands’ continued ties.
