Substandard is a fast food restaurant in GTA San Andreas based on the real-life fast food franchise Subway, with the company's logo closely resembling the 1990s Subway logo. Substandard has two stores; one in Market, Los Santos and another in Santa Maria Beach, Los Santos.
Both stores are inaccessible and play no role in the storyline whatsoever. The name "Substandard" implies that the quality of the business and the food is poor.
