Dirty Dogz Hot Dogs is a popular restaurant in O'Fallon, MO, known for its mouthwatering selection of hot dogs made from 100% Black Angus beef, bratwurst, spicy sausages, kielbasa, smoked sausage, and veggie dogs. With a focus on quality, the restaurant takes pride in using only the highest quality products and preparing fresh condiments every morning. Their commitment to customer service and cleanliness is evident in their attention to detail, as they clean and sanitize their cart and condiment bottles multiple times a day.
Founded by Jason Gaines in 2005, Dirty Dogz Hot Dogs started as a small location in Chesterfield Valley and later expanded to other areas before settling in Monticello Plaza in O'Fallon. With 14 years of experience in the food industry, Gaines decided to pursue his passion for hot dogs and provide a better living for his family and employees. In addition to running the restaurant, Gaines also indulges in his hobby of piloting hot air balloons through his business, St. Louis Ballooning Adventures, which offers balloon rides and participates in competitions and races across the country.
