SAN JOSE A student housing complex could sprout on the site of the former Vung Tau restaurant after a developer paid just under $3 million for the East Santa Clara Street property, according to documents filed on Aug. 25 with the Santa Clara County Recorder's Office. Following its purchase of the former restaurant site at 535 East Santa Clara St. for $2.9 million, Tripalink Real Estate, acting through an affiliate, has proposed a 41-unit student housing development.
