Near the old Hong Kong airport

My friend in Japan was talking about the old Hong Kong airport. This
合成糖水 dessert cafe is actually located near the old Hong Kong
airport in Kowloon. Since the airport moved to its new location, tall
buildings had sprung up around here. Tall buildings were not allowed
in this area before that, and this place used to be the centre of the
Hong Kong triad and the most densely populated place on earth.
