About

From renown Italian restaurateur Mario Iaccarino and The Ritz-Cartlon, St. Louis comes the first official United States venture, inspired by southern Italian landmark restaurant Don Alfonso 1890. Mario’s brother, chef Ernesto Iaccarino, created the menu which features beloved southern Italian dishes that honor the family’s culinary heritage, while showcasing regional ingredients. The color palette, inspired by lavender fields in Sant’Agata, sets a romantic tone for the restaurant where the light purple motif is featured in the cascading wisteria chandelier, hand painted tile in the open kitchen, and even the servers’ uniforms. As a nod to the most iconic monument in St. Louis, arches and curves can be seen throughout the space, signifying a gateway from old to new. The focal points of Casa Don Alfonso invites diners’ eyes to dance through the interior, leading guests on a curated, visual experience like the twists and turns of the city’s converging rivers. Overall, the intimate, yet approachable, space acts as a canvas for the food it presents, evoking a sense of whimsy and possibility from guests’ first steps inside.
