Whats the best and biggest Korean Spa in LA?

What's the biggest and/or best Korean Spa in LA? I've been to Wi Spa and was recommended to try Grand Spa but Grand Spa wasn't as big and didn't have as many rooms as Wi Spa.

Any others I should check out? Also I was told that there's a new one being made but the guy couldn't remember the name. Anyone know the name of the newest facility?
