No, not the creepy alternate reality from the Netflix series Stranger Things.
Unfortunately, though, since Emporium Chicago, which opened the bar, didn't strike a deal with Netflix for the rights to "The Upside Down," Netflix is shutting them down.
Jared Saul, the manager of the Emporium, tells DNA Info there are no hard feelings:
"If Netflix were OK with us running The Upside Down project through the season two premiere & the Halloween weekend we would most definitely have continued this incredible party a little bit longer!"
"...It's been so much fun for us & for fans of Stranger Things & has even introduced the show to new fans here in Chicago who weren't aware of the show before visiting the pop-up."
So if you're in Chicago, you have until the end of the month to check out this cool pop-up. For the rest of us, we'll be able to return to the world of Stranger Things when Season 2 premieres on October 27th.
