Carl,
I was confused by Presidency Club. I knew it as Chembur and never got around to playing it. It has the reputation as being by far the best course in Bombay. At least it used to. I've played the Willingdon Club. Quite a poor course by GCA standards but have not played it in 15 years and it's probably better. Let me know if you need an introduction. There is also the US Club which I played once. It had the narrowest fairway I've ever seen, maybe 5 yards wide lined by trees.
