McDonald’s is testing all-day breakfast
By Matthew Lyle • March 31, 2015
McDonald’s is going to experiment with serving breakfast all day.
The chain will start testing a 24-hour breakfast menu next month at several locations in San Diego, the company told Business Insider.
If the test is successful, McDonald’s could expand it to other markets.
But it could also cause major operational problems.
McDonald’s stops serving breakfast at 10:30 a.m. in most markets because its grills aren’t big enough to handle breakfast and lunch items.
