Located at Saratoga Avenue and Carrollton Street in Willis, the mall is inaccessible to the player. However, an ATM is available for use on the southwestern corner of the mall's exterior in GTA IV, and the mall is a destination for the Taxi Driver side-mission in GTA Chinatown Wars. Businesses supposedly based in the mall include Al Dente's, Anna Rex, Canyon Megaplex, Didier Sachs, Pill-Pharm, Pizza This, and Ranch.
The name of the mall is a possible joke. It refers to the British slang word, "willy", thus creating amusement due to the word "Big" before "Willis" which refers to a "large penis". Whole name read like "Big Willy Small". The mall is centered on the Jamaica Center shopping complex.
