I like to go to the International Market in Reno, NV. Too bad that it is an hour away. They have everything to make all kinds of cuisines: Thai, Chinese, Mexcian, etc. I go there throughout out the year to stock up on various noodles, rice wine, soy sauce, rice vinegar, etc.
Another favorite is Quincy Natural Foods in Quincy, CA. I only get to go there every once in awhile because it is also an hour away. But they have a great selection of organic produce, pasta, and grains, etc.

Abundant Life Natural Foods in Portola, CA just opened up and has a very limited selection of items, but is better than nothing. My mom and I bought some veganaise there and it is wonderful on sandwiches and in tuna or chicken salad. I still don't think I could give up regular mayonaise in certain recipes, but the veganaise is surprisingly good on sandwiches, etc.
In the summer we have a local produce stand called the Sierra Valley Farms that has locally grown produce. I like to go there to get mixed greens, eggplant, zucchini, tomatoes, onions, herbs, honey, etc.
