This building is super warm on winter mornings
If you have the option to pay for your parking via phone app I recommend you do. Getting past the lines at the parking meter is worth the 37 cents service charge. Plus you won't miss your train.
Trax Depot Cafe is delicious! It's open from 4:30a-10:30a
For cab, call Antonio: (847) 338-7510.
Miss a Chicago inbound train after 5pm and you may get stuck waiting 45 minutes to an hour for another.
Nice coffee shop before 8 AM weekdays.
The food is great and so is the staff
