This led me to believe they were raided recently and shut down temporarily. In the bay area, the best places to go are in San Francisco. But keep in mind that San Francisco although has a large red light district, they are not exempt from the law. Sophia's Massage in SF was raided a few times in the past year also. I read somewhere that the mayor of SF is tolerant with adult oriented businesses to keep the prostitutes off the streets.
Most raids occur when near by businesses complain.
Sophia received some complaints and the police came in. Here is something I came up with. When you walk into a business and you have the option to select someone you like, seems pretty safe to me. If there are several girls around and the lady of the house is around also, seems safe. Never let your guard down, but respect the girls and you will enjoy your visit.
