The many Brazilian tourists who choose Miami as a shopping destination know a good deal when they see it. That's why at lunchtime they head to Camila's. There are fancier local Brazilian eateries with more sophisticated food, but the dishes at this unassuming self-service restaurant probably bear more resemblance to what the Brazilians eat in their hometowns. Camila's "super buffet" offers a daily selection of fortifying main dishes, which can include the traditional feijoada, beef stew, pounded seasoned steak, and chicken in spicy sauce. The meal starts at the salad bar, with an array of fresh vegetables and prepared salads. For dessert try the sweet coconut flan or homemade rice pudding, and top it off with strong Brazilian espresso. The atmosphere at Camila's is informal and friendly; there's a mix of casually dressed patrons chatting in Portuguese and young, suited employees from nearby office buildings. The restaurant is immaculate, and the staff is attentive, happy to list the ingredients of unfamiliar dishes or arm you with fresh plates for another round at the buffet. Go ahead and taste everything; the all-you-can-eat meal costs $6.95 at lunch and $7.95 at dinner. Now that's a bargain.
