If they were serving soggy hotdogs, you'd want to come to this restaurant for the view alone. Fortunately, the kitchen is run by Ricardo Costa, one of Portugal's most talented young chefs, and holder of a Michelin star since 2012. His tasting menus are a never-ending parade of superlative mini-dishes—crab ceviche with avocado and black-beer foam; suckling pig with caramelized scallions, chanterelle mushrooms and Azores cheese; and tangerine cream with lime, meringue and mascarpone ice cream were just a few delights we had on a recent visit. The wines chosen to accompany each dish come from the hotel's selection of more than 1,000 tipples, with an emphasis on port and the Douro. Service is an impeccable blend of knowledge, warmth and efficiency. The expansive dining room is bright, light and decorated with murals showing tropical landscapes. Then there's that view. Watching the sun fade to gold over the river and the lights of Porto twinkling in the twilight, is unforgettable.
