A certain amount of fakery going on in these names:
Oh Ya - soya sauce brand (the manufacturer is Sil / Marico)
Ya Hoo - Chinese takeaway near Khar Subway
Ching Ki Shak - Chinese restaurant or takeaway, can't remember location
All of the above were seen around Mumbai.
For the record, I don't think Indian Chinese food is fakery in the sense of trying to pass off something as what it's not; it's just a creative adaptation to a different cultural context, like, er... like Baz Luhrmann's Romeo and Juliet :P
