Justin Sullivan/Getty Images(CNN) - Growth at McDonald's slowed in the third quarter, suggesting that the chain is feeling the heat from competitors who are getting aggressive on breakfast and plant-based menu items.
To improve growth, McDonald's has been adding digital menu boards to stores, expanding delivery options and investing in AI tech for its drive-thrus, among other things.
For instance, Wendy's is adding breakfast to its menu, investing $20 million and adding about 20,000 employees for the initiative.
Others, like Burger King, are exploring plant-based menu options.
McDonald's has plant-based options internationally and is testing a Beyond Burger in Canada, but has yet to test a meat substitute in the United States.
