I really love the food at Defina, but my experience with the service has been a little hit-or-miss. Recently my younger sister treated me to dinner there after we both had a rough day, and we received the worst service! We happened not to be dressed as well as the other patrons that evening (though still respectable), and were somehow totally passed over. Our server lavished attention on the table of four next to us, but never checked to see whether we liked our food, or came back to refill our water. We wound up paying at the bar after a few minutes of trying to get his attention, and got out of there.
In general my experiences have been positive, and they offer GREAT food. But, if anyone from the restaurant is reading this, it is a sign of good service to make people feel welcome even if they happen to be wearing lame shirts, or look like they've had rough days. Hopefully this is just a small anomaly from an otherwise great restaurant.
