- MPMichael PawlowskiOct 1, 20264.0Good truck parking.
- DKDakota KoppingSep 17, 20265.0I’m so glad I had to stop for gas. Otherwise I would’ve missed this hidden gem of a gas station. The homemade looking sandwiches were absolutely amazing. The inside is immaculate. I’m glad I found this spot on my way back to Wisconsin.
- BJBeth JohnstonJul 31, 20265.0Such a cute shop and super clean restrooms!
- JKJanet KonradMay 18, 20265.0Accidentally found this fantastic place! Bathrooms were clean, there was so much cute stuff to brows through and purchase! Food items I have never seen in a gas station before... And egg sandwich: hard boiled egg cut in half with lettuce and tomato... for real!? An actual turkey bagel sandwich! Not one of those anemic mass produced sandwiches! And latte to go! We will be back!
