Looks like Your hunting a RARE Breed there Fellow!!!! It seems like when I come across a review that mentions that the race of the provider is White, the girls are rated as Fat whales & are UGLY!!!!.................That is is U come across ANY reviews that list the race as white at ALL!!!
unforunately, the search here is a lil faulty. I get results from all over even though I used the search while at the LOS ANGELES forum. and advanced search page would be a nice addition (hint hint;-)
The search feature could be improved however it works fine for what the OP asked for. I picked an LA (most definately part of So Cal) Zip code and searched for spas with in 50 miles. It returned over 350.
I then clicked on the links for Ethnicity and selected "White", that left 16 places with-in 50 miles of the zip I chose.
