- ADAthena DedowDec 16, 20255.0This was easily the best Sinclair I have ever stopped at. Food was fresh, bathrooms were pristine, shopping options were great, and they even had an ice cream machine! My favorite thing though was the local coffee shop present in the gas station. They were closed, but had premade cold lattes ready to go with a variety of flavors and they were immaculate! Well done y’all!
- DSDaniel SkeltonNov 13, 20245.0Very clean restrooms and large variety of snacks
- LLLizJun 18, 20235.0Nicest service station I’ve ever seen!
- APAustin PutzJan 12, 20233.0Very nice and new. 2 big problems. No paper towels in the bathroom. They have those two sided blow things made for the hands of 3 year olds so you touch the dirty sides. Would be nice to then offer hand sanitizer at least. Then the ice was watery out of the machine and very tough to press and I'm a man. Probably the one in Holstein still better.
