New York City has tons of these too; they’re just generally not well-advertised since they many of them cater to a specific market. There are a few button stores in New York, mostly in the Garment District, but also on the upper east side. There are stores selling all kinds of obscure art supplies, kitchen equipment, and lab gear too.

To be fair, I’m not sure exactly where you’d buy a currywurst cushion, but there’s a shop selling bones and stuff near NYU, if you someday decide that your living in room needs more of a Natural History Museum vibe.

There used to be a bone store in Berkeley, called The Bone Room. They're online-only now, though, after the death of their founder and presumably also rising rents. (https://www.boneroom.com/about--contact.html)
