I went to Down Under about a month ago with my parents as their driver while they did a wine tasting. The atmosphere in the bar was great. They had a great sense of fun, as it happened to be a karaoke night when we were there. One of the guests happened to bring a karaoke machine in and they encouraged all guests to participate. Even the bartenders had a brief cameo on the mic, showing that they incorporated a fun atmosphere in the bar.
The food was very good considering that they were not primarily a restaurant. I had the ribs, and they were the kind that you would eat to the bone and wonder where they all went when you were finished. The desserts were a little heavier than what I expected, but for a night out it was doable.
The service was great as well. They were very friendly, checking back on our table often to make sure everything was good, and if we needed refills on our drinks.
All in all, a very good place to go for a night out. Not a weekly haunt, but definitely a place to come back to every once in a while.
