The Babylon at its old location was populated with MANY young Thais! It felt like a beehive bursting. Compare that to today when the vast majority of customers are tourists - well, until, of course, covid stopped that too.
Another observation: At the time, the building that was home of Babylon, with its four floors, was the tallest building in this part of Bangkok. It was surrounded by the residences of various ambassadors, each in a large garden with trees. So the building stood out and was visible from afar, especially at night when it was decorated with thousands of lightbulbs, like a Christmas tree. Sitting on the rooftop terrace, listening to live music, having a drink and talking with beautiful people, you could observe the rays of light that emanated from the terrace and illuminated the trees of these gardens. Oh, those were the times.
