Radical City is a large nighttime city with casino elements and a large amount of buildings.
As such, it has many roads and a highway, but is best known for its Giant Pinball Table. Radical City is one of the five courses of the game Sonic R. It hides two Chaos Emeralds and by catching the five Sonic Tokens, Tails Doll is unlocked. The track is the longest in the game and has the least amount of shortcuts. At first the track seems like a factory but slowly shifts gears into a Casino.
The theme song for this track is "Living in the City".
