I have visited many ISKCON temple's in the past and the jaipur one is under construction right now. i like the atmosphere of ISKCON temple's as it's kind of different and funny sometimes.
You will find people from different countries are members there. enjoying bhajans and having fun.
people come from all across the globe in the search of peace and spirituality. I went there on Janmasthami evening and the temple was over crowded.they told it is going to take 5-6 hours to enter the temple. so i withdrew the decision of darshan at the time. but i would surely like to visit the temple again.
