Familiarity, I’d imagine. You go to Chipotle in any part of any city, and you already know what’s on their menu, how much it’ll cost, and how it’ll taste. But smaller restaurants, even a local chain, can vary wildly from store to store, and most people probably don’t want to spend their limited lunch time experimenting with restaurants they’re unfamiliar with.
It is the food of the sea, after all.
