I used to go to Cupertino once a month. Here's my experiences
Edward's is great, but a little ways out like hfearly said.
On the other hand, I scored a 9 year old tin once at Smokers Paradise.
I wasn't too impressed with Mission Pipes, although it's a nice store.
If you're looking for a place to sit, hang out, have a bowl and chat, Edwards is the better choice. For scoring a rare find, Smokers Paradise trumps.
Enjoy the trip.
"The fact is, squire, the moment a man takes to a pipe, he becomes a philosopher. It's the poor man's friend; it calms the mind, soothes the temper, and makes a man patient under difficulties. It has made more good men, good husbands, kind masters, indulgent fathers, than any other blessed thing on this universal earth."
