Dear Aspirant,
I'm not the best person to tell you that because I study mechanical engineering but from what I hear from friends, it's decent.
There are much better colleges in Mumbai for Computer Engineering than RGIT. Most of the staff is helpful. But there are couple of them which will slowly torture you for no reason (But you'll always get couple of them in every college).
The labs are good and lab assistants are helpful. The department is overall strict (You cannot use cellphone on the floor, You've to wear college ID card, You cannot sit on the balcony etc.)
It's not something to regret if you get it.
