The results of the Register's convenience store online poll are in, and while this is an unscientific exercise, two gas stations stood out in the voting for go-to food and drink offerings.

We asked our readers to pick their favorite Iowa gas stations to get coffee, tea, pizza and roller dogs, as well as which c-stores have the best soda fountain and snack collection. More than 2,600 votes were counted.

QuikTrip, the Tulsa-based chain that's had a presence in Iowa since 1974, rated as readers' favorite across four categories. Casey's General Store, founded in Des Moines in 1959, won in three of the categories.

Here's how the votes came in for each category:

Casey's is the king of pizza and it's not even close

Iowan's love Casey's pizza, which has been well-documented. Casey's has been a pioneering force in the development of gas station pizza and has become iconic for Iowa-specific pizza varieties like taco and breakfast. Competition has increased over the years with pretty much every gas station offering its own take on the quick-made pizza.

But Iowans love the classics, and 85% of poll respondents said Casey's offers the best pizza, eclipsing second-place Kum & Go (7%) and third-place QuikTrip (4%).

QuikTrip has got the tea

When it was announced that QuikTrip would be closing four locations in the Des Moines area, there was some outcry among readers: What would they do without QuikTrip tea? The results of the gas station poll support this idea, with QuikTrip receiving 35% of the vote in favor of its tea. Avid tea drinkers in Iowa prefer QuikTrip's fresh-brewed QTea and the several flavors available compared to other gas station's offerings.

Casey's General Store was the second-most preferred with 24% of the vote followed by Kum & Go with 20% of the vote.

QuikTrip rolls over the competition when it comes to roller dogs

Upon finding themselves craving, sometimes against better judgment, a hot dog glistening from its time rolling gently between the warm metal rods, most Iowans (46% of poll respondents) think of QuikTrip roller dogs. Whether it's the classic all-beef, a corn dog or a taquito, Iowans have made QuikTrip the destination for their quick lunch-time fix.

Kum & Go has some support with 26% of the vote while third-place Kwik Star racked up 13% of the vote in the only category where Casey's didn't rank in the top three.

Casey's is the best gas station for coffee

When looking for the bean juice to gas them up while they gas up their cars, 31% of poll respondents voted Casey's General Store as their preferred choice. Casey's Arabica beans, multiple flavor choices and cappuccino varieties put them a cut above the rest in the eyes of Register readers.

The second-most popular choice for coffee was Kum & Go (25% of the vote) followed by QuikTrip (22% of the vote).

Iowans prefer Casey's doughnuts, too

Apparently, Casey's General Store owns the market when it comes to dough-involved foods in Iowa gas stations. Casey's doughnuts have the right texture, the right sweetness in the glaze and maintain their freshness just long enough to make a day-old box worth it at the discounted price.

Once again, Casey's towered over the competition in this category, receiving 55% of the vote over second-place QuikTrip (16%) and third-place Kum & Go (12%).

The soda fountain at QuikTrip is unmatched

QuikTrip takes quite a bit of pride in its soda fountain offerings. How is any gas station soda fountain different from another? According to the convenience store chain, it isn't just a funnel for syrup and water, but a place where "each drink is a perfect combination of elements carefully calibrated to produce the crispest and most refreshing fountain drink possible."

Voters in our poll appreciated that dedication to soda quality, giving QuikTrip 39% of the vote over second-place Kum & Go (29%) and third-place Casey's (15%).

Everyone has their own personal favorite when it comes to snack selection

Nowhere were the poll results more split among Register readers than when it came to snack selection. Everyone seems to have their own preference among the state's most recognizable gas stations when it comes to who's carrying their favorite variety.

QuikTrip placed first in this category, but just barely, with 26.4% of the vote. Neck-in-neck with QuikTrip was second-place Casey's General Store with 25.6% of the vote and nearly tied with third-place Kum & Go, which received 25.3% of the vote.
