Advantage that comes with sitting at a rooftop bar instead of indoors involves enjoying the view. Dallas has one of the most captivating views in the Deep South. You can sit on the rooftop and look at the skyscrapers and buildings that dot the landscape. You can also take in the setting sun as it descends on the horizon late on a Friday or Saturday afternoon. You can also watch the moon come out when you sit outside on the rooftop bar rather than at a table inside of the bar itself.
