Yes! I have indeed sampled many fine Maverik station foodstuffs. I love a good gas station hot case and the Maverik's is top notch.
Of course, if you're a northern Utahn, you've driven to St. George. And everybody who has driven to St. George knows the best gas station hot case in the UNITED STATES of AMERICA is that big station with the statues of elk and stuff in the parking lot on the south side of I-15 just north of Fillmore. It makes me wish I needed to drive to St. George today just so I could stop in Fillmore!
