anyone have luck with full service at these places

Your better of going to their apartments, or hotel/motel.

Of course if the donation is sufficient anything is possible

Look for girls that work out of apartments. Invariably they'll do FS.

The massage girls in the parlors seem to be overly proud of their services. So after you pay the mamasan, get service from the girl you might as well pay an apartment girl $200 and get better service in a more relaxing atmosphere.

Try Thai Betty, can't go wrong with her.

... are tsescorts.com, ts4rent.eu, and trans.eros.com.  There might be some that are LA specific - IDK.

I agree, these 3 seem to be the best. EROS may be higher end.
