McDonald’s is yanking its all-day breakfast menu as the coronavirus pandemic upends its operations.

The fast-food giant is making the temporary change to “simplify operations in our kitchens and for our crew,” Bill Garrett, senior vice president of operations for McDonald’s USA, said in a statement.

The company is working with its restaurants and franchisees to focus on serving its most popular menu items, Garrett said. But another McDonald’s honcho emphasized that the beloved breakfast options won’t be gone forever.

“All day breakfast’s response to this news: ‘I’ll be back,'” McDonald’s USA president Joe Erlinger said on Twitter.

The coronavirus crisis has forced “substantially all” McDonald’s restaurants in the US to offer only drive-through, delivery and carry-out service, according to a Wednesday regulatory filing. Its locations in European markets such as the UK, France, Italy and Spain have closed entirely, though about 95 percent of its restaurants are operating in China, where the coronavirus originated, the filing says.

McDonald’s starting serving all-day breakfast in October 2015 as part of ex-CEO Steve Easterbrook’s efforts to turn around slumping sales. Customers ravenous for hotcakes and McGriddles sandwiches helped boost the chain’s same-store sales by 5.7 percent in the fourth quarter of that year, though the menu’s rollout drew criticism from franchisees.
