Wup et Dux

Wup et Dux is a store appearing in Grand Theft Auto V and Grand Theft Auto Online.

Description
The name makes it most likely a French fashion store. It plays no role in the storyline whatsoever and is inaccessible to the player.

Influence
Its appearance is influenced by the former  store at 420 North. The spelling of the name and its ensuing pronunciation is a play on the slang phrase "what it do".
