OC K Spas
I-Spa in Irvine is great. Clean and safe. Plenty of room, even on busy days / times. Common area very clean, cafe is excellent. The bad news is that it is becoming a little run-down, but otherwise, it's great. Admission is $35.
K-Spa in Buena Park has only been open about 1.5 years, so everything is very clean, new, and very safe. Great common area. an excellent value and place to relax. Admission is $30.
The Spa Hyu in City of Industry is OK. Small by comparison to both I-spa and K-spa, especially the wet and dry sauna in the men's wet area. Only room for 5-8 men. Admission is $35
Visited Yu spa in San Diego for the first time a week or so ago. Small. Over priced. $50 admission, which is included with a massage. Common are is small, too, but has light snacks available as part of the price of admission.
That's my take on OC K spas
