Most of the dishes at Casa Paco are as reasonably priced as they are delicious. Examples are the paella — chicken and rice or rice with seafood — and special house chicken, a tender half-boneless grilled bird smothered with onions, lime juice, butter, and pepper served with white rice and fried sweet plantains. Several kinds of fresh fish are prepared in countless ways. And don't forget the Spanish and Basque omelets. After you've devoured dinner, your belt might be tighter, but dessert is a must. A long list includes flan, rice pudding, homemade ice cream, and crema catalana, whose candied-sugar topping hides a creamy custard.
