Typically gas stations aren't people's first choice for coffee but some places actually do it well and other times people may need gas station coffee when they're on a road trip or in a bind.

In celebration of National Coffee Day coming up on Friday, the Gas Buddy app looked at over 2 million user reviews to come up with the gas station with the best coffee in each state.

Unfortunately the best gas station coffee in North Dakota is not available in the immediate vicinity of Bismarck-Mandan as Casey's Gas station reigned supreme in the coffee category.

The closest Casey's to Bismarck-Mandan are either in Carrington or Jamestown. But Casey's is obviously doing something right because the chain won out for the best gas station coffee in South Dakota, Iowa, and Arkansas too.

Check out the best gas station coffee in each state here.
