Missing stuff that I used to get in CA would imply that 1--I miss CA, 2--I can't move beyond there and appreciate what my new (okay, not so new) home has to offer.
Aside from the fact there are ZERO Mexican restaurants worth a shit up here, I can't think of a thing--and I can make plenty of my own if I really want it that bad.
Then again, try getting lobster rolls or grey corned beef in CA.
