Hotel restaurant's service quality is an extremely important competitive policy to maintain customer support and build a strong customer base. Efforts by hotel restaurants to win and retain customer loyalty by providing enhanced quality services are ever evolving and becoming increasingly challenging. This research attempts to examine the relationship between hotel restaurant's service quality dimensions, customer satisfaction and customer loyalty in four- and five-star hotels in Amman, Irbid, Madaba, Dead Sea, Petra and Aqapa in Jordan, where most of the hotels in the country are concentrated. The evaluation of hotel restaurant service quality is adapted from the SERVQUAL model. For the purpose of achieving the objectives of this research, questionnaire surveys were used to measure customer satisfaction and customer loyalty.
