Buffalo travel tips

1) Find Greece in Buffalo with Albright-Knox Art Gallery

Albright-Knox Art Gallery on 1285 Elmwood Avenue in Buffalo is a nice place to experience featuring paintings in styles such as Impressionism, Cubism, Surrealism, Abstract Expressionism, and Pop Art by artists such as Pablo Picasso, Henri Matisse, Joan Miró, Jackson Pollock and Andy Warhol if you are a culture vulture. Even if you are not, you can just admire the building itself. Being a magnificent neoclassical building, it is reminiscent of the Erechtheion in Athens.
