The course takes place on a rainy evening, and the city is strongly lit up. The whole course takes place in an elevated area, rather than on a road on the lowest ground (like previous city courses, such as Moonview Highway and Mushroom City). Therefore, drivers can fall in certain places (specifically where there is no railing). Puddles of rain can be found in certain areas on the track, which are a hazard and can slow the player down. Like all other courses in the game, there is an area eligible for gliding. The track also has a blimp and a screen to show the ads and the race itself. The ground is slippery making it harder to turn.
This course takes parts of other songs in the Mario Kart series. The song is a remixed version of Toad Circuit (also Mario Circuit in this game) and the theme song of Mario Kart 7. It also consists of portions of the Mario Kart 64 game's Toad's Turnpike and the Mario Kart Wii game's Mario Circuit and Luigi Circuit.
There is a shortcut in this track. Before the blue gliding ramp, the player should see the Koopa Clown Car blowing gust of air upwards. If the player veers to the left whilst gliding, they should get blown upward by the Koopa Clown Car and safely reach the other side.

The new Bowser insignia that is now used in this course is also modeled around a hexagon. The blimp with a screen on it has been removed. Billboards now show an animated picture of the name of the course, along with Bowser in it, instead of displaying an ongoing video of the player's point of view, an animated ad, and a still picture of Bowser. The rails with scrolling neon arrows have been redesigned into neon rails with light arrows on top of them.
The course layout is roughly the same, but with a few changes. A drop-off has been added at the entrance to the tunnel, the U-turn near the end has been modified into an anti-gravity section, while the water puddles in that section are removed, and the air current found near the S-Bend has been moved to behind the banner, instead of beside it. The music is also roughly the same, similar to DK Jungle and Grumble Volcano, but an electric guitar has been added. Bowser's minions - Paratroopas, Dry Bones, Hammer Bros., Fire Bros., and Boomerang Bros. - are spectators for this course. In addition, like in the rainy courses in Super Mario 3D World, rain drops flow down the camera lens, just to add minor effect.
