For context, Siam Paragon is the biggest mall in Bangkok though, and one of the biggest in Asia.
As Southeast Asians, we don't have many options for recreational activities during the weekend. Families and couples often choose to spend time in malls (for dining, movies, and the air conditioning) rather than going to parks, for example. It is hot and humid here most of the time by the way.
When you look at the number of posh brands in a gigantic mall like Siam Paragon, it's quite abundant and staggering, from retail shopping to casual dining. There's one for everybody.
