To preface my review, I think your perception of this botanical garden really depends on which season you visit. When I went, in mid-April, it was still quite cold and the garden wasn't even charging admission in the outer exhibits. The feature was pretty much just the insectarium and the butterflies. I mean...the former was kinda good (but very small) and the latter could've been experienced for free at Changi airport in Singapore. Sure, there were a lot of butterflies, but it was kind of overkill. The line to see them was way too long and it was a bit underwhelming. I think it would've been cool to see the Chinese and Japanese gardens but they were unfortunately closed.
Eh.
