Two of my favorite pizza places in Lexington are Puccini's and Mad Mushroom.
Puccini's Smiling Teeth is located in Chevy Chase and has AMAZING pasta in addition to their pizzas. I have been there many a time and scarfed down their house salad with a pizza or pasta. The thing I love most about Puccini's is the casual atmosphere. You could see friends from college or families dining with their kids.
Mad Mushroom, not to be confused with Mellow Mushroom is one of those late-night treats that you can't imagine unless you experience it first-hand. Cheese sticks. Dipped. in. ranch.
You can't tell me that you went to UK and never had the cheese sticks late at night.
