"The terms food critic, food writer, and restaurant critic can all be used to describe a writer who analyzes food or restaurants and then publishes the results of their findings."
"Food critic" and "restaurant critic" are in practice synonyms, although there is still a distinction to be made. Both suggest a critical, evaluative stance that often involves some kind of rating system. The distinction, if any involves the range of possible investigation. "Food critic" has a more contemporary vibe, suggesting that restaurants, bakeries, food festivals, street vendors, and taco trucks are all fair game."
