Interesting to absorb this point for the first time. As I think about it, it mirrors my experience, but Pepe's has always been a tough case for me.
Decades ago, I had a white clam pie that lives in memory as one of the best eating experiences I ever had. The crust had a perfect balance of crunch and chew that had my jaw in a tough exercise routine the entire time. The following day, I felt the awakened muscles, as though in the aftermath of a great workout. All the flavor of the pizza was pure pleasure throughout.
It's quite likerly a chased dragon that I'll never catch again, so it's almost unfair to arrive with that memory. Because of this, I almost only go to Pepe's with people who come in from out of town, have never been, and it's their choice. They usually love the pizza & the experience, while I usually register that it didn't measure up to that perfect time. If pressed, I mutter that it "wasn't transplendent," but do not elaborate.
