This is one of the best large-scale dining rooms in western Puerto Rico, as well as the main restaurant for the largest hotel and casino in the area. The food has real flavor and flair, unlike the typical bland hotel fare so often dished up. Known for its generous lunch buffets, El Castillo serves only a la carte items at dinner, including seafood stew served on a bed of linguine with marinara sauce, grilled salmon with a mango-flavored Grand Marnier sauce, and filets of sea bass with a cilantro, white-wine, and butter sauce. Steak and lobster are served on the same platter, if you want it.
