There are two reasons to pop into the two-story showroom Hay House. The first, and most important, is that this is one of the best places to see what’s new and interesting in contemporary Danish design. The store is filled with cool, colorful stuff, so much so that getting out without buying something can be a challenge. The second reason: From the upper floor you can take in a great view of Amagertorv, one of the city’s prettier squares.
