I finally checked out this store after months of meaning to go in there, and I'm so glad I did. I love their stuff. This beats the heck out of the supermarket spices. And they are reasonably priced too - about the same as what you'd pay at the grocery store.
If you are dieting or trying to eat less salt, you need to RUN, not walk , to Penzey's. Their spices add so much flavor to food. The Chicago Steak Seasoning is fantastic, adds a nice smoky flavor to everything. They bill it as a seasoning for any grilled item, but I put it on a meatless pasta the other day and it was fantastic.
I also bought smoked spanish paprika. I am pretty sure that is my new favorite spice.
The danger is this store is that it's gonna make you go out and learn to cook new things just so you can use the spices you bought :-)
UPDATE:
Years and many trips to Penzey's later, my current favorite spice blend of theirs is Sunny Paris. It's so good on veggies, but I've even been known to toss it into ramen :O
The staff is super helpful. I was looking for grains of paradise which Penzey's does not stock, and the ladies gave me two places to go which did stock grains of paradise. Thanks Ladies!
I'm upping them to 5 stars :)
