Examples:

“No need to panic, but the Billy Goat Tavern changed its hamburger bun. For most restaurants, this wouldn’t matter in the slightest. But few places in Chicago have changed less over the past 40 years than the Billy Goat Tavern. … Personally, the only thing that could make me disavow eating at the Billy Goat is if they got rid of the condiment bar. Along with no seasoning, the burgers always still come out unadorned, leaving you to load up on toppings however you see fit.” — Nick Kindelsperger, The Chicago Tribune, 10 Nov. 2022
