California's $20 wage for fast food workers is just a few weeks old, and the effects on workers and customers are beginning to emerge.

At Chipotle, the law drove a 20% increase in wages for its restaurant staff in the Golden State, the company said during its earnings call on Wednesday.

To offset that cost, menu prices notched up about 6% to 7% for customers in California, CEO Brian Niccol said.

Restaurants for months have said menu prices in California would rise as the state raised the minimum wage for fast-food workers. Now they are following through.

Consumers picking up burgers, burritos and chicken sandwiches at chains in the Golden State are grappling with prices that for months have been rising at a faster clip than in other states, according to market-research firm Datassential. 

In response to recent minimum wage increases in California, fast food restaurants across the state are shifting to automation to get rid of wage-earning humans.

The move to making customers place orders at digital kiosks alleviates what owners say is the financial strain of rising labor costs after the minimum wage for the state’s fast food workers increased on April 1 from $16 to $20 per hour.
