U.S. air travel continues to be snarled on Christmas Day, even as the massive winter storm system has moved on.

Few national restaurant chains will open their doors Sunday for Christmas.

The big picture: Major chains including Chili’s, Taco Bell, Chipotle, Olive Garden and Outback Steakhouse are closed for the holiday while McDonald's, Starbucks and Dunkin' are open.

The hunt is on to find last-minute Christmas gifts and missing ingredients for your holiday meal.

Threat level: Brace yourself as most stores, including grocery stores, are closed for the holiday while many convenience store chains and drugstores are open Sunday.

Finding a store open for last-minute Christmas gifts and groceries or a restaurant to grab a meal will be a challenge Sunday.
