The below Twitter thread, initiated by Brent Toderian, is a great collection of some of the "best streets in the world." https://twitter.com/brenttoderian/status/1153742040221356032?s=21 I would encourage you to click through and have a scroll. The one thing that you'll likely notice about almost all of the contributions is that the streets tend to be fairly dense/urban and they tend to be oriented around the pedestrian. No surprise there. My only qualm with some, but not all, of these streets is that -- while beautiful from an urban design standpoint -- many of them can feel quite touristy and/or commercially generic. They are the street you go to when you're visiting the place, but they are perhaps lacking in urban authenticity. I don't mean to take anything away from the beautifully designed streets in the above thread. In fact, some of them aren't at all commercial and are simply magical places to be -- period, full stop. See, for example, La Condensa (neighborhood) in Mexico City. My argument is simply that the natural cycle of cities and neighborhoods sometimes means that the best streets for new ideas and small businesses are maybe not the most beautiful ones. Part of this is a function of rents and part of this is function of the fact that the best cities are constantly reinventing themselves.
