About us

O’s American Kitchen features hand-crafted menu items using fresh, quality ingredients that change the expectation of the traditional casual restaurant. Our American kitchen is influenced by local, regional and global flavors… with an O’s twist!

Variety is the spice of life! Our menu not only offers variety but quality and preparation seldom found in a casual-dining restaurant.
