I'm actually a big fan of Speedway. If you weren't aware, they recently renovated the place and made it quite a bit nicer on the inside.
The employees are always friendly and after awhile you will get to know them by name. They seem as though they are always happy to answer your questions or help you out.
As you would expect, they have your standard array of gas station "delights." I would say that they have a much bigger selection of candy, chips, soda, and alcohol than most other gas stations do. One thing I really like about this Speedway is the milkshake machine. It actually allows you to blend your own milkshakes. If you're in the mood for a hot food item, go to the front of the store and you will see their "Roller dog" hot dog stand and the warm sandwich stand. If I'm not mistaken, they also have Pizza.
