The Wisconsin-based Culver's restaurant chain, known for its Butterburgers and fresh frozen custard, has surpassed the 600-location mark. Five restaurant openings on, December 5 in Gainesville, Florida; Grovetown, Georgia; Marion, Illinois; Mount Juliet, Tennessee and Mesa, Arizona, put the chain over the milestone.

Culver's is currently in 24 states with Georgia and North Carolina joining the expansion in 2016. Plans are to close out 2016 with 43 new Culver's restaurants. Forty-four more are planned in 2017.

Culver's was founded on July 18, 1984 in Sauk City, Wisconsin, by co-founder Craig Culver and his family. Today there are eight company-owned restaurants with the rest owned and operated by independent franchisees.
