European zoo restaurants are generally FAR superior to North American zoo restaurants, although this photo shows what I first thought was either an animal stable, a barn or a storage shed! Inside it is probably amazing, but the exterior doesn't make one's stomach anticipate a gourmet meal.
This is one of the renovated original buildings of the park in the times that it was a fancy house, probably it was a shed back then... There is also a modern restaurant near the zoo entrance, that might be more to your taste
