Not only the absolute best Mexican restaurant I've ever visited, but the best restaurant ever. Rick Bayless' Frontera Grill offers perfect ambiance, with cozy, colorful, warmth, combined with mouth-watering aroma of grilled food items filtering the air. Sit at the bar and enjoy a smooth margarita with an imported tequila. Dining service was impeccable. Our waiter said he has been with Frontera for over 20 years. He communicated food menu expertise and displayed great timing throughout our meal. Authentic and truly original food items. Make reservations in advance, or arrive early (4:00 PM or before), and stand in line. Doors open at 5:00 PM, but the wait is well worth it.
