Celebrity Chefs Mary Sue Milliken and Susan Feniger give Mexican food a few new twists at Border Grill. You'll certainly find standards like tacos and enchiladas, but most dishes have a bit of a twist to them. There's an definite emphasis on sustainability here with organic black beans and humane certified, antibiotic and hormone free meats and poultry. The Border Brunch happens every Saturday and Sunday from 10 a.m. to 3 p.m., when you can indulge in unlimited small plates for $38.99, or bottomless mimosas, micheladas and Bloody Marys for $20. You'll find plenty of dishes with Border Grill's signature style: Yucatan Egg Benedict, for example, with a manchego cheese biscuit, Yucatan roasted pork, a slow cooked egg and hollandaise sauce, plus pickled onions. The vibrantly decorated restaurant overlooks Mandalay Bay's pool area, and its colorful ambiance lends itself to casual meals.
