I recently had it on draft at Xoco in wicker park which is a Rick Bayless restaurant and found a 6 pack of it at west lakeview liquors. Hope this helps!
It'll be somewhere, just hard to say exactly when and where. I would suggest hitting up Binny's Lincoln Park one of those days. I've had good luck finding it there on Wednesday and Friday before. If you find bottles at a store, just do the right thing and buy some other stuff too! It's a great beer that I love, but there are plenty of other things you should grab some of while you are in town. I think it's relatively easy to find on tap somewhere, too, if you're just looking to try a pint or two. I know Kuma's had it on tap today, along with the others mentioned above.
Hi Braddaniell, My wife barely tolerates my passion for beer and if she saw me trading it would probably take things to a whole different level It appears zombie dust is a little easier to come by lately. Check out beer menus to find it. Good luck! https://www.beermenus.com/beers/9797-three-floyds-zombie-dust
On draft, you can find at it Hopleaf vast majority of the time. But like @beerjunk said, bottles is a different story.
It's easy to find it on draft, but bottles not so much like an above poster said. In case you strike out at a lot of places trying to find it, you'd likely find it being sold at Fischman's. It was definitely being served in the bar area, though I surprisingly didn't see it being sold in the bottle store half. Maybe one could talk someone into selling it to go?
If you are around Bottles and Cans, they get their Three Floyds shipments in Wednesday afternoons. They are never totally sure if they are getting Zombie Dust, but it seems like in the past few weeks they have gotten some in. Worth checking out or keeping an eye on their Facebook page, as they'll make a post late afternoon on what they got in that day. Be warned, though, it tends to go fairly quick (gone that evening), even with a one six-pack/customer limit. Good luck!
For draft use beermenus.com, as for sixers call along with others mentioned warehouse liquors in south loop has it today, so worth a call if downtown.
