想唱完k去奧海城,邊間近,同埋搭咩車去?

There will have no answer for your question because

1) you have not told where will you sing Karaoke,

2) the wordings above are very contradictory. If you aim to reach Olympiancity, there is only one such Plaza and you need not ask which one is closer. If you talk about Karaoke in Olympiancity, you need to ask how can you reach this Karaoke from Olympiancity.

Hence, it is impossible to offer help with limited and insufficient info.
