Hello shezu007, I would recommend you to check these two threads in the gambling section. None of them have extensive reviews, but they are definitely a good way to start your research. Also, and I know you just asked for casinos, but if by any chance you enjoy sports betting, please take your time to step by my thread as well, about sportsbooks rankings.

Here are the threads:

https://bitcointalk.org/index.php?topic=2097255.0 (Overview of gambling sites)

(And my thread about Sportsbooks)
