As a restaurant, I have no comment since I haven't eaten at Rumjungle. I will however comment on my experience for those who want to know about the nightlife. A friend of mine and I went there on a Thursday night a few months ago. Even though we were staying at the hotel, we still had to pay $20 admission! Never again! We got in there and the clientelle was really random. Quite a motley crew. The music was dated and the dance floor is on a raised area which is way too well-lit for the type of patrons. There were a few clueless dudes following me around in a stalker-like fashion - oblivious to the ring on my finger. That didn't help the evening! My friend and I ended up retreating to our room to drink there since the scene was pretty bad.
Rumjungle was really cool about 5 years ago but they need to give up and find a new club to put in there. It's just not hip anymore. There are so many other cool clubs in Vegas - don't waste your $20 on Runjungle.
