Yishun stadium you mean? i always book in advance... but i guess if there is a table available can just do a walk in... but there is a risk of no table available though... however i did saw a table tennis table at one of the void decks in yishun
I am planning to play table tennis with my friend at Yishun Sports Hall this weekend Saturday 21-June.
3hrs morning or afternoon session.
As long as you can rally can liao =)
Any1 interested just pm me.
