B&K Rootbeer

B&K Rootbeer is a regional American drive-in restaurant chain whose identity is built around draft root beer, root beer floats, and classic drive-in fast-food service. The chain operates in the Midwestern United States, particularly Indiana, Michigan, and Ohio, and its restaurants are independently owned and operated rather than managed as a centrally controlled corporate network. The brand’s origins are associated with Melvin and Mary Bergerson and with Wabash, Indiana. Reference material identifies the first B-K restaurant as having been built in Wabash in 1940, while also describing the chain as having been founded in the mid-1940s. The name B-K is explained as an abbreviation of Bergerson and Kenefick. During its expansion period, the chain reportedly reached approximately 238 drive-ins in Indiana and surrounding states, making it a substantial regional presence in the postwar drive-in restaurant era. B&K restaurants are distinguished less by a broad national product system than by a recognizable service format and signature beverage. Customers traditionally receive food and drinks through a drive-in setting, with draft root beer and floats serving as the central consumer draw. The concept belongs to the same broad American restaurant tradition as curb-service hamburger stands, but its durable recognition comes from preserving a localized, nostalgic format rather than pursuing nationwide scale. The brand’s ownership history includes a period under DeNovo Corporation of Livonia, Michigan, whose president was David Chapoton. In the late 1980s, Chapoton sold the B-K trademarks to Burger King Corporation. The transaction connected the B-K marks with Burger King’s development and launch of the BK Broiler grilled-chicken sandwich, although B&K Rootbeer remained associated with its own regional drive-in restaurants. In 2016, Burger King abandoned the B-K trademarks. David Hosticka of Michigan subsequently sought to retain or re-register the marks, working with patent attorney Jake W. Lombardo of Bolhouse, Baar & Hofstee, P.C. The application was rejected by the United States Patent and Trademark Office because the B-K lettering was still registered to Burger King Corporation. The trademark episode illustrates the tension between a small regional restaurant network and a larger national company that had acquired related marks. B&K Rootbeer is therefore best understood as a heritage regional restaurant brand rather than a conventional packaged-beverage company. Its historical importance rests on the survival of independent drive-ins, the continuity of draft root beer service, and the preservation of a Midwestern roadside dining experience. Reference material indicates that approximately 35 locations remained around the time of the 2016 trademark effort, although a current location count is not established here.

B&K Rootbeer developed as a Midwestern American drive-in restaurant chain associated with Wabash, Indiana. Reference material gives 1940 as the year in which the first restaurant was built, while describing the chain’s founding as occurring in the mid-1940s. Melvin and Mary Bergerson are identified as founders, and the name B-K is said to represent Bergerson and Kenefick. The early business emerged during the period when curb-service restaurants and roadside drive-ins were becoming an important part of American food culture. The chain’s defining feature was its draft root beer, served directly at the drive-in and used in root beer floats. Although B&K restaurants also served conventional fast-food fare, the beverage program gave the brand a distinctive identity. Its operating model was regional and decentralized: restaurants were independently owned and operated, allowing individual locations to preserve local characteristics while sharing the B-K name and concept. At its height, the chain reportedly included 238 drive-ins across Indiana and neighboring states. This expansion made B&K a notable regional restaurant system, though it did not become a nationwide competitor to larger hamburger chains. The brand’s appeal remained tied to Midwestern communities, roadside dining, and the nostalgic experience of ordering food and draft root beer from a drive-in. A later phase of the brand’s history involved DeNovo Corporation, based in Livonia, Michigan. David Chapoton served as the corporation’s president. In the late 1980s, Chapoton sold the B-K trademarks to Burger King Corporation. The sale created an unusual connection between a small regional drive-in identity and a major national restaurant company. Burger King subsequently used the marks in connection with the launch of its BK Broiler grilled-chicken sandwich. The trademark transfer did not eliminate the independent B&K restaurants. The surviving locations continued to operate as regional drive-ins, while the legal status of the marks became increasingly important to efforts to protect or revive the brand. By the 2010s, reference material described roughly 35 remaining drive-ins, a substantial decline from the chain’s reported historical peak. In 2016, Burger King abandoned the B-K trademarks. David Hosticka of Michigan attempted to re-register the marks, with assistance from patent attorney Jake W. Lombardo of Bolhouse, Baar & Hofstee, P.C. The stated purpose was to support the remaining restaurants and potentially revive the B-K Root Beer brand. The United States Patent and Trademark Office rejected the application, citing the continuing registration of the B-K lettering by Burger King Corporation. B&K Rootbeer’s history consequently combines regional restaurant expansion, independent ownership, trademark transfer, and heritage-brand preservation. Its continuing significance lies in the restaurants that retained the drive-in format and in the association of B-K with draft root beer and root beer floats. The available reference material does not establish a current corporate owner, centralized headquarters, official website, or complete present-day location list.

  B&K Rootbeer became associated with DeNovo Corporation of Livonia, Michigan, led by president David Chapoton.

A regional heritage drive-in brand centered on draft root beer, root beer floats, and independently operated Midwestern fast-food restaurants.

• Beverage

  Draft root beer

  Draft root beer is the brand’s signature offering and the product most closely associated with its drive-in identity. It is served from restaurant fountain or draft systems rather than positioned primarily as a packaged retail beverage. The drink functions as both a standalone refreshment and the base for the chain’s floats.

• Dessert beverage

  Root beer floats

  Root beer floats combine B&K’s draft root beer with ice cream and are one of the chain’s flagship drive-in offerings. The float reinforces the brand’s classic roadside-restaurant positioning and differentiates it from fast-food chains whose beverage programs are centered primarily on cola and other nationally distributed soft drinks.

• Quick-service food

  Drive-in fast-food menu

  B&K restaurants serve traditional drive-in fast-food items alongside their beverage specialties. Available reference material characterizes the chain as a hamburger and fast-food restaurant system but does not provide a complete standardized menu. Individual locations may therefore vary because the restaurants are independently owned and operated.
