Margaritas Mexican Grill & Cantina is outdoor dining at its best! Located behind the Rio Condos, along the Wisconsin River, this Chula Vista restaurant not only offers a spectacular view, it has a fresh, fun Mexican menu that is sure to fill you up after a day at the waterpark. Open during the summer months, Margaritas is fun for the whole family. Our menu is filled with flavorful Mexican cuisine of fajitas, salads, sandwiches, and kid favorite tacos and burritos. Of course, this restaurant was named after the most popular menu item on the menu – jumbo Margaritas!
