Seneca One Stop is a popular gas station and convenience store located near the border, known for its affordable prices and variety of offerings. The staff is described as friendly, and the location features a Dunkin' Donuts with both in-store service and a drive-thru. While the gas prices are generally lower than in Ontario, the quality and cleanliness of the bathrooms have been a point of concern for some customers.
