Turn into the building signposted with Gazprom’s headquarters and head for the lift in the left side of the blindingly sleek Quartro Corti business centre. You will be greeted six floors up with a candid view of the nearby golden dome of St. Isaac's Cathedral. The interior is understated and the glass walls ensure that the view is the main focus. The cuisine is as crisp and modern as the restaurant in which it’s served and shouldn’t disappoint even the most discerning guests. Classic European tastes dominate, though Asian influences are also given some attention and the fresh fish based dishes in particular come highly recommended.
