I recently had dinner at the Hilton Inn restaurant (airport, Alcoa Hwy). The service was excellent. The food was "Excellent!" The Hilton Inn Knoxville airport has made a concerted effort to upgrade the quality of their dining; it shows and it worked. Food - excellent [I had the steak; it was prepared in the manner I had asked. WOW!]; service - excellent [the waitress was prompt, courteous, knowledgable, and most helpful.]. THE DINING AT THE AIRPORT HILTON INN is a QUALITY RESTAURANT.
