I generally try to stay away from dinners at a hotel. I opt for more local, traditional fare. One exception, however, is the Armillary Grill at the Hotel Intercontinental Doral in Miami. The menu is extensive and includes items that represent the local diversity. They also feature special menus throughout the year. For example, famous chef La Pepa from Spain is visiting over the next couple of weeks as guest chef whipping up incredible Spanish fare.
I live in Miami and often choose Armillary Grill for a great meal. My favorite appetizer? The tomato soup is AWESOME! They've taken a simple, comfort food and made it a must-have!
