There used to be a restaurant in Seattle, WA. that had the same concept going, although on a much more traditional level.
They closed in 2000. The Iron Horse
and in Sumpter. OR, The Sumpter Junction Restaurant, had a full on NG layout (behind glass) running all over the building, but was not used to serve.
The Junction Diner in Forest Park, IL. (Chicago) has a similar setup as The Iron Horse, but really small in comparison. Much more geared to families with small children.
There's a restaurant in Raleigh, NC called "Dos Taquitos" that does the same thing as Prague, but a much more festive place.
All the video clips for that locale are on TikTok and Facebook, can't share here.
