They have some nice looking stuff though I've never purchased from them. Think it would work well with standard 28mm and perhaps even the older 25mm.
Another option is the Rock Ridge line link
They make some nice furniture and scatter terrain, as well as a lot of buildings. It's all laser cut. But be warned, their stuff is more of the big western scale, more like 32mm. It's a bit largish for 28mm, but works well with some of the newer heroic scales. The casino and pool hall stuff is nice.
Tiny Furniture (https://tiny-furniture.com) also has some neat stuff you can use for Old West for taverns and such, though some of it is kind of medieval looking. She's out of the Urals, Russia, so mailing takes a while. Useful food items, too.
I used some stuff from both sites, and then scratch-built the rest of the interiors in my town of about 36 buildings. You can see some of the casino stuff at TMP link It's mostly underneath the zombies.
