McDonald's to test all-day breakfast at some locations in San Diego area starting next month

McDonald's is going to start testing an all-day breakfast at some locations in the San Diego area starting next month.

The company said in a statement on Monday that the test is in response to customers who have said they'd like to eat breakfast foods outside the typical morning hours that they are served.

The test will include a partial menu and feature some of McDonald's breakfast sandwiches and hash browns.

Shares of McDonald's Corp., based in Oak Brook, Illinois, added $1.11 to $98.07 in afternoon trading.
