This is indeed a good location for both tourist and Local Thai. It is a combination of cultural and modern themed waterfront which focus on Food and Shopping.
It is easy to reach by taking Free shuttle Boat from BTS - Saphan Taksin ( on your left handside from BTS toward central pier).
This is also the place where famous cabaret show -Calypso located. If you plan to visit this place together with the show. I would suggest you to reach Asiatique at least 3 hours before the show to wander around the place.
Leaving Asiatique could be a pain. You will see super long queue to travel back to BTS. Taking taxi is another pain and most taxi won't take meter. It happen to my friends where they have been charged double even though they only went in after confirmed it's metered taxi.More
