I have been going to Luna's for 30 years or so and will continue to do so. Why? Consistency. I never worry about what day of the week it is, or what cook is working that day. My favorite is the Eggplant Parmigiana. Dinner comes with freshly baked bread and soup or salad.
It is somewhat noisy but I think this is because most of the people are repeat customers and they are more relaxed. Expect to wait a bit if you get there after 530pm, maybe 15 minutes or so, it tends to fill up very quickly but is worth the wait.
