Officially called the “American Bar” but known to locals and design lovers around the world as the “Loos Bar,” this swank drinking spot was built in 1908 by Adolf Loos, a pioneer of modern architecture. Arguing for the reduction of architecture to its essentials and the use of the finest material instead to suggest sensuality, Loos layered the ceilings, walls and floors with black onyx and dark marble and is refined by sleek brass fittings.

On most evenings, young media and arty types squeeze in to enjoy “American-style” cocktails (read: fancy and high potency). Loos referred to the bar as “American” after having resided in the United States. Many Americans, however, would be bewildered at the comparison after witnessing the cramped smoke-filled room.
