The best view of the St. Isaac’s Cathedral dome is the main reason to climb to the top floor of Quatro Corti business centre, which houses the Mansarda restaurant. The business centre itself is also a landmark of sorts, an example of modern architecture integrated into historic ensemble of St. Petersburg. Visitors come to Mansarda smartly dressed; typical orders consist of oysters, wine, scallops, king crabs and fois gras.
