Well few options to look at.
1. Princeton Review
2. Manhattan Review
I would not recommend any others in the city. Most of them make copies of the OG or the MGMAT books and run the classes. There are quite a few companies now in Hyderabad that have Review somewhere in their name. So, you will have to be careful before you make a decision on any review
I have not taken coaching personally, but I have been to both places when I had a plan of taking the GMAT. I am considering taking coaching later on this year. Manhattan seems to be talking a lot of about their results. I dont see much chatter from princeton on their top scorers. I even saw someplace where Manhattan sponsored a scholarship of 2 lacs to some student. I called to see what that was about. Guess they had it last year. Not anymore. The quality of the material at manhattan seems to be far superior than princeton. Each of them has their strengths. But only someone who got the training from either of the places can talk about it. You should visit both places, and then decide for yourself.
Good luck. Post your feedback here once you visit them. Would like to know your experience.
