King Power Mahanakhon

Occupying the first four floors of the Mahanakhon skyscraper, this vast duty-free outlet is run by King Power, a Thai duty-free company that also owns Leicester City, the English Premier League club. No more having to wait until your return flight home to splurge on some excise-free goodies – you can even claim VAT refunds on pricey buys at a ground-floor counter.
