the korean palace girls and service are very good, they were my favorite choice for 3 years
I only had one bad experience with them in my three years using them
unfortunately the bad experience with also my last experience
I didn't know it for one year, but the girl had complained that  thought I was taking pictures of her.
which I absolutely was not
I had taken a break for about a year, and then when I got back into the swing of things, I called kp, but they would not return my calls for about a month
finally I spoke to the manager, who explained that I've been banished
I also then later learned, that kp posted a negative review about me, which caused several providers tonight even answer my calls.

I would recommend searching the ad boards, or Rs 2k, I have found a few enjoyable alternatives in the meantime, but unfortunately nothing as steady as the Korean palace

Chicago is kind of dry lately so good luck

You can try Thai Spicy Girls. Most of their girls are very nice especially Paris. But make sure you are a member of roomservice 2000 or they won't see you. Plus their 1 hour rate is reasonable.
