I hesitate to even reference them specifically because I know I'm going to get overwhelmed by folks raving about them, but there's that donut place in the West End that's supposed to be the absolute best donuts in the city, and they sell out by like 9am every day. Why in the world would I ever go there? In literally every other city I've ever lived in or visited frequently, if you ask what the "best" of something is, you are reliably told about a place that operates like a normal business that you can just...go to. When you ask that question in Pittsburgh, though, the answer is always some place in a neighborhood you've never heard of, somehow it's never anywhere near you (no matter where you live), they're only open for 30 minutes one Thursday per month, and they accept every currency except the US dollar.
