While tapas remain at the heart of COA’s approach—encouraging connection, curiosity, and shared experiences—the menu has expanded far beyond small plates.

From a perfect midday escape to a leisurely evening meal, the inviting patio is open all summer long. Lunch is fast, fresh, and flavorful—featuring a tapas menu, salads, entrées, and a ‘choose your own’ combination with a variety of sides.
