Check out this photo that is nearly 100 years old! Cardinal2007 from the San Jose Development Forum gives a great description below of what you see in this image and what exists today.
"1st St, and San Antonio. The Montgomery Hotel on the left was moved south to make way for the Fairmont Annex, currently Muji is at that location. The entire block to San Fernando was redeveloped on both sides, the Fairmont Hotel is on the south end, and the building that says Pacific was replace by the Knight Ridder Building. On the right is a 2 story office/data center with retail on the first floor, a reuse of the failed Pavilion Mall. The building to the right south of San Antonio is still there, currently apartments, the movie theater wraps around it. Between San Fernando and Santa Clara on the right is most of the same buildings on the left some where redeveloped, one burned down, and is now an empty lot owned by the Archdiocese.
The light rail tracks are roughly between the tracks and where the cars are parked on the right. The old tracks are long gone."
