We’ve all had those mornings where we just NEED that last minute cup of coffee while on the road. Not all brews are all created equal, though, so popping into one chain restaurant for a steaming mug of joe may mean you get less wired than if you ordered somewhere else.
Take the below infographic from Sleepopolis, for example. By looking at the caffeine content of different chain restaurant coffees, they were able to figure out which spots will get you the biggest wake-up boost. When it comes to some of the big names, like Dunkin’ and McDonald’s, their coffee just seems to fall short while some surprise names like 7-11 are relatively strong.
At 17.5 mg of caffeine per fluid ounce, 7-11 easily trounces some of the biggest names in coffee in terms of strength, including Dunkin’ (15 mg/fl oz), Panera Bread (11.8), and McDonald’s (9.1).

Only Caribou, Starbucks, and Coffee Bean & Tea Leaf have more caffeine per fluid ounce than 7-11’s brew, making the ubiquitous convenient store a prime choice if you need to get wired without dishing out a ton of cash.
In comparison, an average cup of coffee has 12 mg of caffeine per fluid ounce. That puts Tim Horton’s and McDonald’s, two of the most ubiquitous coffee spots out there, below average in terms of caffeine content. Why that is, only one can guess.
