Rainbow Island Restaurant 55 Bill Drake Way, Pacifica, CA94044 Rainbow Island is an eclectic Asian restaurant by the sea. Tucked under a colonnade across the street from a busy…More shopping plaza, the unassuming entrance belies the sprawling interior. Inside, perhaps a dozen tables and a dance floor stretch into the shadowy rear of the main room. The restaurant regularly hosts banquets, wedding receptions and bridal showers. While the decorations suggest Chinese kitsch, the menu offers dishes from as far afield as Thailand, Malaysia and Singapore. The restaurant also does brisk takeout and delivery business.
