King Power calls itself the ‘king of duty free’, and it’s not difficult to see why. Quite aside from the fact that they hold the monopoly for such services in Thailand, their range of wares is very impressive. It includes high-end fashion labels like Hugo Boss, Calvin Klein and Pierre Cardin; top-notch jewellery like Omega, Rolex and Longines; cosmetics from Clinique, Estée Lauder and MAC; electronics from Canon, Sony and Apple and much more besides. It’s not just international brands, either. There is an impressive range of Thai crafts and souvenirs to choose from, too.
