The Promenade set was one of the first things I worked on, and here's a pretty mediocre concept sketch:
I remember I thought it would be cool to have a monorail running through the set, lol.
The whole thing fit on Stage 17 on the Paramount Lot, and here's a blueprint of the set:
On the lower right side you'll see the name of the Set Designer, and in this case the set designer was Nathan Crowley, a very nice Englishman who ended up being Production Designing the last Batman trilogy for Christopher Nolan.

Here's an image of the set from an episode:
