You need to be more specific!
Do you want full service? Asian? Caucasian?
I heard good things about A Lady’s Touch but they’re restrictive and pricey but the girls are good looking.
Go through Leolist, Backpage and Craigslist(although Craigslist is frustrating as a few Asian shops spam ads)
If you find a girl that seems to be good search her name and number(last 4 digits) on here.
Read the reviews.
Are you restricted to downtown only? Roxanne’s has some good reviews but nothing recent!
