Kolme Kruunua is one of the few restaurants in Helsinki where the demographic of the customers ranges from twentysomethings to over 80-year-olds. Some of the elder customers who remember their fathers spending time at the restaurant, now, in their twilight years, enjoy the atmosphere of the place themselves.
In mid-1990s, the old wine bar was replaced with a bar counter, but otherwise the original interior with its wood paneling, old lamps, glass paintings and glass decorations has been preserved.
