Clayton’s is a restaurant located in the Triad Plaza on Mexico Road in O’Fallon, Missouri, formerly Rizzo’s. We specialize in continental cuisine; steaks, seafood, chicken and pasta. We are a fine food establishment, in contrast to a ‘fine dining’ restaurant. To that end, our entrees are served as a meal and not in an a la carte fashion. We are open for dinner Tuesday thru Sunday. Established in 2016.
