hm? in subways?

but now that u mention it. it is actually true   lack of toilets and rubbish bins

now u can use it as an excuse to check out the award-winning toilets at those chic eating places in hongdae

Glad to hear that. I am very particular about toilet. 

of coz their subway got toilet..some very high-tech lagi.. 
if not,tourist attraction also got public toilet,shopping malls as well..no worries..
