They had everything I needed! The staff was friendly, available and helpful.
One of my favorite parts of the store is that all the ingredients have around one paragraph of description on them, including items like the origin of the ingredient and possible uses. I'm always afraid that I'm going to buy the wrong type of chili pepper (which is ridiculous because I would never in a million years be able to tell, I eat so few), but Penzey's descriptions helped me pick one that was appropriate for my dish (I picked an Indian pepper for my vindaloo).
I'll be returning soon, and likely many times after that.
