I have been to Bangkok three times and on those three times I have only visited Siam Paragon, Central World and Gaysorn. Of the three, I've got to say Siam Paragon and Central World are my favorites.
I love Siam Paragon because they have a big food court. The food choices is just amazing. I get lost whenever I go there. There's this Thai food stall that we always go to whenever we're here in Bangkok. The food is unbelievably delicious, they serve fast and most importantly the price is very affordable. I just always forget to take a picture of this stall. And of course, there's the Royce Nama Chocolate stall as well. I bought two boxes this time.
Another reason I love Siam Paragon is because the designer bags are located there: Chanel, Burberry, Gucci, Jimmy Choo, etc, etc...I get to window shop every time I'm there. And it's already enough for me. LOL!
I love Central World because all of my favorite clothing stores are there: Zara, GAP, Promod, Mango, etc. And since it's a huge mall, every corner is a surprise. One minute I am in the women's clothing area, the next minute I am looking at stone sink. And I get to exercise just by going around the place. It's also not too crowded. I love it.
Maybe next time, I'd explore MBK and Emporium Mall.
