That bar you saw under Turbhe flyover is indeed the infamous Rasna that has been discussed quite a bit on this thread.
As for Kishore and Mayur, reading the last 50 pages of this thread would have provided you the google map coordinates. A few minutes of upfront research could have saved you a lot of time and frustration. BTW, Kishore is not in Sanpada, it is located in Nerul ("Ganesh Vadi Road, Sector 1, Shiravane, Nerul, Navi Mumbai").
For your convenience, here are the coordinates for:
Mayur: (Note that it shows up on Google Maps as G R Enterprises)
3278+HV Sanpada, Navi Mumbai, Maharashtra, India
Kishore Bar and restaurant: (Note that these coordinates are for Axis Bank ATM, which is diagonally opposite the bar).
22WC+X3 Navi Mumbai, Maharashtra, India
There are at least 4 other bars on the same street within 100 meters of Kishore (on either side - north and south). feel free to explore them when you get a chance.
