The subway can't go directly. It takes a long walk to get there. The taxi was about 115 baht from GRAND CENTRE POINT TERMINAL 21, but the taxi driver halfway increased the price to 250 baht. Asked the staff, there is no food and drink inside, go out to the street. There are a lot of interesting things in it, including this rope net array which I can't name. It has run many places, and I only saw it in Canada before. What's more, such a good place is free.
