Reliable gallery on Albermarle Street(the Picadilly end), which specialises mostly twentieth century art including Picasso, Chagall and Matisse as well as impressionist works. The gallery has a continuously changing stock of paintings, so it is always worth popping in to see what they have on the walls. It also has an interest in Scandinavian art, something of a rarity for galleries in the area. They also have a steady schedule of exhibitions, including Boaz Vaadia currently, and with Warhol, Henry Moore, Arman and Marquet as previous shows, you can sense the breadth of their collection. Friendly staff and a welcoming space.
