First of all a good thread to kick things off. It was my first time that I attended Pycon India and the experience was truly amazing and NOT to forget the quality of food!! My take is that NIMHANS is perfect for Pycon but I am guessing seating capacity is the issue we can surely check out the following : [http://goo.gl/vHmpyN] : Also one of my friend suggested the following [White Orchid Convention Center in Hebbal]. I have been to this convention center and it's quite spacious. 

@Jaysinh Shukla I think it's better if we would stick to Bangalore for the next year too. And there are number of reason(s) for the same. Firstly, this year I saw Pycon was extremely well organised reason being volunteers and other people involved are accustomed to Bengaluru. But don't take me wrong if anybody wants to suggest any other city he/she is welcome to do so provided the activity graph related to event(s) related to Python is quite high, pre-run up events etc. 

p.s This is my personal opinion.
