My first trip to Chicago this week.

Can some of you locals make some suggestions?  Preference is for 25-35, 120lbs. or less, slim and petite.  Good reviews inside.

Thanks in advance.

Not sure where you will be staying, but for suburbs try Autumn,
link to her reviews:

If you're downtown, you've got to try Sercye.  She's incredible!  A one in a lifetime!  Search under Chicago reviews.
