Mario’s Cafe is an excellent destination for breakfast, lunch, and dinner.
For a restaurant to offer breakfast, lunch, and dinner takes a lot of dedication and quality staff because the menu varies with different dishes. Takes talented cooks and a strong kitchen team for food prep and more. However, the restaurant owner is a seasoned restaurant owner who has built a strong reputation operating restaurants.
The owner of Mario’s also owns Dos Primos Mexican Restaurant, located at 624 N Main Street, in O’Fallon, MO.
Mario Parra is the owner, and he also owns Dos Primos Mexican Restaurant, located at 624 North Main Street in O’Fallon, approximately one mile north on Main Street. He has operated that establishment since 2004, and it has been a great success for him and his customers.
