I thought the building was very nice, especially with that circular atrium in the middle.
They actually have lockers where you can leave your things, so that you won't have to lug around your bags while exploring all nine floors. The main galleries are located at the 7th, 8th, and 9th floors. I definitely enjoyed the photos showing how Bangkok used to look before all the modern developments.
There are also shops where you can buy books, accessories, and souvenirs such as shirts, aprons, etc.
The best part about BACC is that entrance is free, so you can enjoy all those without spending a single centavo.
After that, we headed to the mall to check out some books at Kinokuniya. It's always such fun to visit this place, with the wide range of titles they have. I got a few books, then we we went back to the hotel to finish packing and check out. We thought it would be best to go to the airport early, as the rains might mess up the traffic again and cause us to miss our flight.
That was one fun trip and I'm definitely happy about the chance to visit Thailand again. It was one of the first countries I've ever been to since I got myself a passport, and it's definitely special to me.
