Steak ’n Shake said on 29 August that its latest round of restaurant remodels was paid for with Bitcoin, highlighting the fast-food chain’s growing acceptance of the cryptocurrency as a treasury asset and funding tool. The privately held burger-and-milkshake brand did not disclose how much Bitcoin it deployed or how many locations were refurbished, but stated that the digital currency helped finance upgrades ranging from interior design to kitchen equipment. The company also referenced the use of rendered beef tallow—normally a cooking by-product—as another source of funding, underscoring its bid to market the revamp as both innovative and in keeping with its menu heritage. Steak ’n Shake’s move comes as food-service operators seek new ways to finance capital expenditures and lure customers with refreshed formats. Industry analysts say investments linked to cryptocurrencies remain uncommon in the sector, making the chain one of the first U.S. fast-food operators to publicly tie renovation spending to Bitcoin holdings.
