Do you guys know meditation center in India, preferably not far from Bengaluru, that would specifically aim for stream entry, 2 months retreat ? 

Bump

Panditarama lumbini in Nepal would be the most obvious (far from bengalore obviously, but you can get by bus from the north, have you thought of Sri Lanka?) , but I would let more knowledgeable chime in! (I heard about a monastery -tibetan or Theravada?- somewhere in the south, anybody?)Good luck and metta

It is not for me personaly, my colleague got interested, so i figured out, you guys have the most experience and if you go to retreat you need to aim for minimum stream entry.

What would you recommend in Shri Lanka?

​​​​​​​Thanks for feedback, really appreciate

Go find a hermit in the wilderness  who doesn't advertise.  They would be the real deal

Here is a recent thread with a few links.. I have not been there myself.
What is your friend's experience? Has he any? Shooting for SE might not be the most realistic goal for a beginner (nor going straight on a two months retreat)... Just saying, might work as well, who knows?
I meditate in the Goenka tradition, they do intense ten day retreats (too intense according to many here). If your friend is reasonably self sufficient, it might be an easy option for him as you've got them all over India (here is one in Bangalore), and it might get him in interesting territory whatever that is...
I will let others ponder this recommandation as it is tangent to your queery...
He could also go to Kerala and spend a few weeks in Amma's ashram. She's usually around at this time of the year (she is right now, just checked, and it gets VERY busy when  she's there) and it is an intense (for some, life changing) experience in a more classical indian guru tradition.
Well, that's all I can think of at the moment!
Your friend should ask directly maybe...

Lets assume that none, at least he was in AP teritory from the short description that he gave me.

Totaly agree, I remember there was some kind red flag guide why you are not ready to go to retreat.

I will ping him to give his opinion/practice/expectations etc.

Many thanks, smiling stone!
Your meta reminded me rock scene from everything everywhere
