Loop Lunch has been an /r/chicago tradition for a few years now, but it's always been organized on Facebook. This group seems like a great place to move it since we can have it recurring.
What is loop lunch? It's a way for /r/chicagoans in the loop to meetup each week and enjoy a lunch together. Pretty simple stuff.
The Thompson center is great because it's fairly centrally located, and it has a lot of food options. We typically wait from 12:15-12:20pm for any stragglers, then go downstairs to get our food. We eat way in the back in this hidden area with lots of free tables.
If you work in the loop, you should definitely check it out! We do this every week on Tuesdays.
See you there!
