Steak 'n Shake, a U.S.-based fast food chain known for accepting Bitcoin, announced its expansion into El Salvador, a country renowned for its Bitcoin adoption. The announcement followed the company's participation in El Salvador's Bitcoin Histórico event. Steak 'n Shake began accepting Bitcoin in May, attributing an 11% rise in Q2 same-store sales to this decision. The company recently faced backlash from the Bitcoin community after considering accepting Ether (ETH) as payment. Despite a favorable poll result, Steak 'n Shake decided against adopting ETH, reaffirming its commitment to Bitcoin. The company reported a 15% increase in Q3 same-store sales, outperforming competitors like McDonald's and Starbucks.
