We live by The Shamrock & used to eat there at least once a week, but my wife & I have seen the quality of the food (which had always been excellent) go steadily downhill. You can still order the same things, but what you get is not the same high quality as it used to be. The service is still above average, the staff is always very friendly, and the place is always very clean, but without the food quality being what it used to be, there's really no reason for us to dine there anymore.
During our last visit, we were also charged for our cola refills, which we felt to be in extremely poor taste. We made the decision not to dine there anymore, which is really too bad. It used to be one of our first choices for dining out.
