On Sunday April 29th I will be in town attending the WWE event at the Allstate Arena. My question is, with the event ending aprox 9:30pm and so by the time I would get out of there, get a cab to the Blue Line my guess is it would be after 10pm. I will be staying downtown more than likely. So is it safe to take the Blue Line at that time of night back to The Loop? Or would the expensive cab ride back be a better choice? This is my first trip to Chicago.
