You won't confuse Passyunk Square, the up-and-coming neighborhood between Washington Avenue and Tasker Street, for Paris, the City of Light. (Paris, for example, has no Pat's and no Geno's, either.) But the two have more in common than Paris might want to admit:
* A massed planting of London plane trees. In Paris, they shade the Champs-Elysées. Here, it's the entire length of the Wharton-street side of Capitolo Playground. The Capitolo planetrees (a street-tough sycamore) are among the 500 street trees planted in the neighborhood within the past four years. An allee of cherry trees near Pat's King of Steaks has been in glorious bloom this spring.
