The question is what are customers perceptions generally about any hotel restaurant. What are perceptions? What will the customer perceive when intending to visit a hotel/restaurant. In other words what will they base their assumptions on. Hope I am making some sense.
Do you mean what factors people look at when choosing a hotel or restaurant, how they decide whether it's good? You won't get a general answer to that, it varies from person to person. Some factors might be: cost, hygiene, friendliness of staff, variety of choice, recommendations from friends, and so on.
