If you are coming in from ORD to Evanston, do not use a city cab. I cannot stress that enough, do not use it. They, by law, have to charge you double or something like that if you are not going to somewhere in Chicago. Call in a suburban cab. American Taxi is a popular one. The flat rate is $31 from O’Hare to Evanston. https://www.americantaxi.com/ATOnlineOrderWeb/main.htm
