Where to find mini bottles of Malört between Willis Tower and Grant Park?

I’m in Chicago for work and looking for mini/airplane sized bottles of Malört; ideally somewhere between Grant Park and Willis Tower (those are the big landmarks I’m seeing on Maps lol).

My fiancé and I love Malört (yes I do actually like the taste, he’s more of a vibes guy). Long story short I have a way to get it blessed by the Pope (probably the only Pope to ever try it?) for our wedding shot but it needs to be in a mini-bottle form.

Any help would be most appreciated!
