There was a subway station in Paris - Etoile I think - that was like that: No need of 90 degree angles, stairs here and there in unpredictable locations, and colorful and brightly lit underground "strip mall". A bowling alley or something. Most subway stations are mostly corridors populated only with people and wall poster advertising, while that one because it had a bunch of stores and other venues, felt so much larger and confusing from a navigation point of view.
Some glimpses of it in the movie Subway I think? It's not the main station in that movie, which is Chatelet Les Halles - vast spaces where it's hard to keep track of orientation yes, but seemingly very simple vertically: flat. Which is misleading: most Paris subway stations are complex vertically because of the need to straddle and connect different sides of rail tracks crossing at different levels, while leaving intact different sides of other tunnels, sewers, etc.
