> While I'm not familiar with sysco as I'm not in the US, these are just chain-y generic and cheap eateries that are frequented by families/people that just want something predictable and cheap?

Chain restaurants of the sort supplied by Sysco in the United States encompass everything from cheap fast food and diners to “fast-casual” to mid-range “sit down” restaurants. Even upscale steakhouses will source things like side dishes (particularly potatoes) from them.

It’s going to suck when that single point of failure supply chain breaks down, but capitalism is antithetical to resiliency, so.
