Yes, Penzeys has locations all over the country, and not just in Pittsburgh. But this particular location is just wonderful--it's spacious and the atmosphere always seems calm, a nice respite from how claustrophic Penn Ave can get on the weekends. (Visit the Penzeys location in NYC's Grand Central Terminal--it doesn't have the same vibe at all.)
Let me be blunt: I like smelling things. The nose knows. So I love that Penzeys has sample jars of every single spice and flavored extract. The store is always neat and well-organized, the staff friendly and helpful. And when it's summer and you're as hot as Hades, the store is always delightfully cool.
You can even buy gift sets of spices for any cooks/bakers in your life. (Hint, hint? No? It was worth a try.)
