I really like the washbasin. Non-adventurous ones can just scoop water from the bowl to wash. Me? Of course I just can't wait to play around especially so when nobody was around. Found that one just need to tip the horizontal bamboo 'hose' downwards and water will flow out at that end. It returns to its horizontal state once the water level in it refills.
Ahhh if only I have the funds and space to transform the boring washrooms at home to something like this. *sighs*
Oh, for those who may be guessing, this is in Gonbei Restaurant, Starhill.
