Maybe, here's a try at Bishan, right across where I lived. (Picture above the description.)
First and foremost, meet up with your friends at the Bishan MRT station.
If you guys think it is still too early to be part of the white elephant, "Junction 8" is always a good choice to hang around, settle your "makan" at one of the many eating outlers inside this shopping mall.
If you think the price is not right at the mall's eating outlets. The coffeeshop, right above the bus interchange, would offer you guys a better option.
Still too early for you guys? The newly-opened library is just next door (but warning to you all - it's pretty noisy at times despite being a library!!)
But the sunse, it's time to head to the stadium via this slope...
Aren't you guys relieved that you filled up your stomach by then? So as to avoid those bland stuff provided by the operators?
Despite their very best effort to wipe out "free-loaders", there's still many ways to enjoy the match.. Ooops
If you felt a bit uptight at the main stand, open gallery like this is a best option (and it's more cooling too).
