Border Grill Mandalay Bay
Mary Sue Milliken and Susan Feniger are the popular, green-minded chefs who created this cheery, sophisticated outpost of their now-closed Santa Monica restaurant. Service is snappy, and you'd be hard-pressed to find a tastier margarita in town—particularly the blood orange and chili-citrus versions. Starters include three citrusy ceviches and plantain empanadas, and grilled sustainable fish and hormone-free meats, such as short ribs and marinated pork, make healthful, flavorful fillings for tacos and tortillas. The all-you-can-eat weekend brunch, served from 10 to 3, features creative small plates, such as horchata French toast, diablo chicken with a churro waffle, and cajeta churro tots with cinnamon and raspberry sauce.
