Excellent rep in Chicago area, easy to deal with and prices are right also.  Recommend without reservation.  Nikki is great help and will be honest in dealing with the agency.  I have used them more than a couple of times.

If you find a girl from SY's that meets your tastes, don't have any reservations about booking through this agency.

Nikki who runs SY's is great.  She won't sell you a bill of goods on a girl just to get the appt. In fact she's steered me away from booking with certain girls because she knows my tastes and thought I would be better off holding out for "so and so" girl. That's what I call customer service

Her girls vary in terms of services offered. Check the reviews on this board, they are pretty accurate. But all her girls are honest and nice to deal with.
