Barney's is THE dept store for niche in Chicago.
Nasomatto Pardon. Wow. Bought it.
If you do downstairs at Barney's in NYC, below the cologne selection on the first floor, they have a lot more stuff that is rypically considered unisex. iE Malle, Labo, Diptyque etc.
I've found Barney's SAs to be very generous with samples, making them on the spot. No doubt helps if they know you are buying, or have bought from them.
So, not the fragrance counter right off the men's department? They had a lot of those brands, plus stuff liek Serge Lutens, when I was in there a few months ago.
