The christ University auditorium is always my favorite place, as it's big enough and I guess has a seating capacity is 1000+ audience with balcony seating available. The stage is also designed wonderfully and the sound proofing is really good.
When I was a student there some 13years back it was there. Well maintained auditorium. Only thing of concern for students and faculty is lot of crowd and too many security personnel near the entrance when an external event happens in an otherwise overcrowded college/university.
