No SB until Palava! There is a couple of DBs right at the shilphata Junction 200 meters away. One is Masti Nx if you take right at the junction while coming from Navi Mumbai. Other one I cant remember the name and also not sure if its operational, so dont trust me entirely here. I am telling you the scenes 8 months ago. If you just cross Palava and toll and drive 1km off Badlapur Highway taking right from Katai Naka, you will find 3 DBs/OBs and the famous one is Rukmini out of the lot. If you are specifically looking for SBs, there are couple, right outside the Kalyan Station West above Neelam guest house but don't even dare to go! One will die looking at the hygienic condition. Even If someone offers me, this is the last option before you die, I would like to die virgin, so you get the idea Since you dont want to travel further, the last option is Raja Bar 50 meters from Ambarnath Railway Station West. Pure SB! My recommendation is to stick to Sneha, Sai Darbar and Mayur !!! Cheers! Bond!
