There had been a popular Italian restaurant in Sai Kung for many years. Not near the water so not directly competing with the lobsters and fish folk. I think only open evenings.
With increase in mainland tourists over past few years the general climate in SK changed. The mainlanders seldom ate there but did crowd the streets. So the landlord saw all the people coming to SK and up went the rent.
That resto is gone now. Who could pay HK$300 for a plate of spaghetti, which is what might have been needed to cover the costs?
