[SF Chinatown] Chinatown Food Memories

Do you remember what was at 655 Jackson (Sam Lok, Z&Y) in the 60s? That was the second Chinese restaurant I remember eating at in SF Chinatown, in 1964, on my second trip ever to SF. I remember it was so crowded so we had to sit at the table right in the front window, a bit traumatic for my unassuming family.
