Nexus of the universe

I realized that the Times's potato leek gratin and The Argula Files's tortilla española had virtually the same ingredients, and that revelation gave me a taste of the serendipitous thrill Kramer experiences when he ventures to Lower Manhattan. "Hey, I'm on First and First. How can the same street intersect with itself? I must be at the nexus of the universe!"
