I am the one who like walking and seeing new (and creative) department store. In Bangkok might have … a little too much in my opinion. Well, most of them are pretty much the same. With brand names, movie theatre, super market, cafe, big name restaurant (mainly Japanese food), etc. As they grew bigger and bigger, the direction of each floor may not enough.
Here is (maybe) the solution from the store, which is the map of department store. So you will not loose track while you shopping or do not need to ask security guard where the toilet is. In the same department store (in the picture) also has golf car available for customer to go around (in case your legs are tired) too.
Not sure what is next innovation, creative ideas, and marketing of BKK department store. I am look forward to seeing those amazement.
