I recognize that place in the first picture. Yuen Kee noodles joint in Tsim Sha Tsui.
It seems to me you had a wonderful time in Hong Kong. But Hong Kong as a destination is only good for a short stopover.
Steep retail prices, subpar services and most shops coming out of the same mould selling same or exact goods on the same street make Hong Kong a rather boring or unfavourable place to stay for a long time.
