Now that house music is mainstream and majority of the more popular clubs play it, I always appreciate some good old hip hop. As I'm not a huge fan of Hakkasan itself, this room is a great alternative. Yes, you will be packed like sardines, but I'm willing to make that sacrifice for hip hop any day. I like the layout of the Ling Ling room because you can walk around the dancefloor to the bar without stepping on toes or being stepped on.
The area where the tables are is a bit awkward because it looks like an audience, but I guess it works for those that would rather sit than dance.
