Kai Tak was described as an IGS (Instrument Guidance System)rather than an ILS, still had the same components but rather than a 2 or 3 degree offset, it was (from memory) 47 degrees! I have sat on the checkerboard by the G/S transmitter and seen the LLZ aerial below in a field, while watching various operators 'attack' the runway in a variety of manners, some pretty ... some not!
Genoa 29 & JFK 22R are also offset
