is whataburger open on christmas eve

That's a great question. I don't believe What-a-burger is open on Christmas Eve, but it's always best to check with the local restaurant to confirm. Some establishments may be closed for the holiday, while others may operate on a limited schedule or with reduced hours. It's also worth noting that while many businesses do close during the Christmas holiday, some grocery stores and convenience stores may remain open to serve customers who need last-minute items or just want to pick up some last-minute snacks.
