It is well-known that this restaurant owes its name to Bilbao's Guggenheim Museum and has also been open for two years. The establishment shows the same modernity as the building that houses it. The dining room is completely modern in design and build. The chairs are a creation of the famous museum's architect, Frank Ghery. As you can imagine, it is essential to book well in advance. Apart from what's on offer on the menu, customers can choose from three different special menus: one classic, another contemporary, and the third based on seasonal ingredients. Here are some suggestions: Roasted Cod, Glazed Cutlets, Crunchy Red Thistle with herbs and Iberian Herbed Pork. As far as the desserts are concerned, they are all so good it's impossible to choose!
