The city of Chicago had set June 3 as the date restaurants can open for patio service. I only have a few of these listed as of Saturday night. We can expect more of these to be announced much closer to the exact date, so I'll add them as I find out. No doubt there are many local and neighborhood hurdles to clear, and not the least of them is finding space for outdoor seating in some streets.
No doubt some of these reopenings may be delayed owing to the current unpleasantness in downtown. I will try to keep up with changes as well as additions.
