COA offers authentic Mexican cuisine and fantastic margaritas, wines, beers, and south-of-the-border fruit juices. Milwaukee restaurateurs Marc and Marta Bianchini created COA from their delight in the taste and accessibility of food served by Mexican Street Vendors. The large windows in the 100 seat dining area look out onto a generous patio, where the weather is tempered with a 6-foot-wide stone fireplace. COA honors the traditions of Mexican urban culture by including in the menu beef, pork, chicken, seafood and a wide selection of vegetables, rice and beans accompanied by flour or corn tortillas. Choose your shell, choose your filling, and choose how many. Buen provecho!
