I have been to the Ballantyne location of Duckworth's many times, as it is down the street from me, so very convenient location. Great beer selection and mostly basic pub type food are on the menu here. Food is ok at best for me. I have had good and bad, but maybe I am just picky. The one drawback is that it gets crazy busy during peak hours and consequently very loud. Not the best place to have a quiet night out, but they have great beer special, which is 3$ pints on most of their 80 or so taps.
As far as service is concerned, I have had good and bad, but I will say that it has been great the last 3 times that I was there, even when it was crazy busy.
Best time that I had at Duckworth's was when I went for a few late night drinks on a Saturday recently with the wife after going out to dinner somewhere else. It was on the way home, so easy enough to pop in. There were a few people watching some late night college football games, but for the most part it was a relaxed atmosphere and the service was great.
