Each individual hotel does it differently. Some have table service. Some have assisted buffets. Some just throw a paper bag at you with a muffin and banana. The brand is mostly irrelevant to how each hotel decides to proceed.
It isn't relevant to generalise.... Check the individual hotel threads and/or Tripadvisor if you are planning travel.
