Going hungry will never be an option at UK. There is a wide variety of your typical national chain restaurants in Lexington, many of which are just a short drive from campus. But by far the most impressive choices are the original-to-Lexington places that are close to campus, like Joe Bologna's and Pazzo's. Tolly-Ho is a must-do for anyone new to campus. Be sure and tell them you've never been there before, and they'll give you a special surprise.
The area around north campus features several ethnic restaurants such as Indian, Thai, and Middle Eastern cuisine. You'll run out of money long before you've run out of places to eat. Don't forget to get ice cream and go for a walk around campus to work off those extra unwanted calories.
