It used to be better earlier, still good to visit. Interesting place to spend couple of hours in hot afternoon or during rains.
Strangely you have to take stirs to go up and down, not sure how people on wheelchairs can visit.
There were lifts but were closed.
Still one of the must visit place in SG, just outside you can take a stroll at riverside and even walk to Merlion and Esplanade.
