West Berkeley International MarketPlace ("WBIM") is a volunteer-based business association created by and for local business owners located on San Pablo Avenue, spanning Delaware Street to Bancroft Way (at the moment). The goal of WBIM is to work with local merchants to promote positive commercial activity, support the local community, arts, events, and encourage a thriving economy in the neighborhood. 
The district is home to a wide variety of local businesses, international food scene with an impressive assortment of new eating and drinking establishments, artists, furniture and clothing stores. We are proud to have such an international presence in the up and coming west Berkeley.
