Best bet is to pick out a few that are at a convenient location for you, and then visit them to check them out. If the lady is an old granny (assuming you don't like old grannies), then simply walk and check out location B and C. Realistically, often times they will be unattractive mingers, but some are decent to good, and on rare occasions you'll find a gem. It's a lot more work, but it's the best way to satisfy an oriental fetish on a budget. And if you find one you like physically, service is generally good with most oriental providers.
