I don't know what percentage of companies use the lunch in an on-site interview for evaluation, but definitely some do. Either with express feedback into the process, or because it's the hiring manager taking the person to lunch, and this is shaping their opinion.

I suppose some could also use it as a refresher break, from their battery of antagonistic one-way LeetCode hazings, or a chance to give the person a more comfortable feeling about the company (not otherwise permitted by their hazing process).
