Terminal 21

This mall in Bangkok is designed to look like an airport, complete with a shopping guide that looks like a passport. You can even check-in for your upcoming flight on the main floor. Explore the nine-story complex and its themed floors that will transport you from Tokyo to Istanbul to San Francisco, all in one day. When you're ready to refuel, head over to the Gourmet Market for a delicious selection of Thai food. Make sure to grab a Tourist Privilege Card from the information counters to enjoy discounts at participating outlets. For a more intimate experience, you can explore the mall and other attractions on a private tour of Bangkok. – Tripadvisor
