Oh, now that's a question that's a little harder to answer! You see, most coffee shops are closed on Christmas Day, but there are a few that stay open for the die-hard coffee lovers. You could check out Starbucks, which has a few locations that stay open all night for the caffeine addicts. Or, there's always the option of getting some instant coffee and brewing it yourself. Either way, you'll definitely be able to get your caffeine fix one way or another!
