Gnocchi is a fashion brand featured in Grand Theft Auto: San Andreas and Grand Theft Auto IV. Implied (by the inclusion of the flag) to be an Italian brand, it is a likely parody of Gucci.
The brand is prominently introduced in GTA San Andreas in the form of a non-interactive store located in Rodeo, Los Santos. The Gnocchi name is also used for a watch that Carl Johnson can buy in the Victim clothing store, being available in gold and silver.
In GTA IV, there are Gnocchi branded shops in Back Passage in Suffolk, Algonquin, and their products are advertised on billboards throughout Liberty City.
