Café Mattolaituri was built by the sea, near a former rug washing pier (hence the name) on the southern tip of Kaivopuisto park. It is open from spring to autumn. All customer places, totalling 200, are on two terraces: one on the shoreline in front of a little building, one on its roof. The building itself contains a bar and staff facilities.
Piers and boats, the islands off Helsinki and the sea horizon afford the customers views that change during the course of the day and year.
