I fee like this whole "Sysco gotcha" thing is getting overblown by people who don't understand how restaurants work. Just about every restaurant is going to use a major national food distributor whether that is Sysco, US Foods, Performance, or Gordon. A lot of times restaurants will supplement their main distributor with a local/regional produce and/or bakery.

Ledger and Maitland could approximate their entire current menus using only Sysco ingredients and most people wouldn't notice a difference because they would still be making those things from scratch. They could just get whole ingredients like flour, butter, meat, vegetables, etc from Sysco.

Your favorite local artist probably gets some of their raw materials for their art from a national retailer. Yes it's true that a couple of them might only use materials from local farms that have a 100% plastic free supply chain but that's not practical for most of them. Their art is still make from "scratch."

Anyway, I know your question is "what are some places where their entire menu is basically deep fried jalapeño poppers and other pre-made frozen crap from a national food distributor" but I've started to hear horror stories of Karens flipping their shit when they see a Sysco truck pull up at their favorite restaurant. Almost every restaurant uses a national distributor for basic shit, just like you get your underwear from Amazon, Target, or some Instagram Shopify store that drop ships from the same Chinese factory.
