I have been to Knitter's Studio a couple of times, mostly because I was already in Menlo Park. I wouldn't make an effort to go there -- in fact the other day I knew my LYS was closed so I went all the way to Los Altos to find another one, skipping Knitter's Studio entirely. They have the organizational scheme I hate -- organizing yarn by color rather than brand. I went in one day and asked for a rather standard yarn store yarn, and not only did they not have it, but the employee I talked to said "We can't carry everything ..." like I had asked for something rare, which I had not. And they do appear to have a lot of yarn, just most of it appears to be novelty yarn and how many scarves can one person make?
