YES they have it at Bay Cities Deli in Santa Monica. DiCecco brand, $2.79 (ish) for a 1lb bag. It's my secret ingredient for all my baked pasta dishes (FORGET elbow macaroni! ugh!) & everyone loves it.
I used to find it everywhere - but now its getting difficult to find. Barilla sells it under a different style name "Cellentani" and it is also called "Serpentini" - go figure. Pretty much, if you call a store, it's a good idea to find out all the possible names for the pasta shape first, and be able to give them a really good description of the pasta.
