Steak 'n Shake reported double-digit sales growth after beginning to accept Bitcoin via Lightning. According to Bitcoin Magazine, the chain launched this capability last year and claims that business has noticeably improved.

For the crypto market, this serves as an example of an attempt to integrate Bitcoin payments into everyday retail trade. However, the source is presented only through metadata and a brief summary, so specific figures, the comparison period, and the separate contribution of Lightning are not disclosed.

The next useful signal would be primary data from the company: revenue trends, the number of Bitcoin transactions, and a comparison with similar restaurants without this payment method.
