RORY: I can’t believe you got into a fight with Pete.
LORELAI: Hey, you do not suddenly decide that garlic is an extra topping, not after five years, not after all we’ve been through.
The first mention of Pete as the owner/manager of the pizza store which Lorelai and Rory frequent, they have apparently been customers there since 1997, ever since Lorelai bought her own house. We met Joe delivering their pizza in “Kiss and Tell”, and Lorelai ordered a pizza from Joe in “The Break Up Part 2” – perhaps Joe is Pete’s son, and it’s a family business?
The bag Rory is carrying seems to have Bell Pizza written on it, but later the pizza store is called Antonioli’s Restaurant and Pizzeria. There is a Bell Pizza in the Los Angeles suburb of Bell, however.
