Though bar hopping and rating a certain place wether it is best or not depends on the person's preference or taste. But here in Doha, it is like a simple quiz to find out which is the best due to a very few choices of bars and lounges in the city. Just eliminate those cheapy bars base on your personal experience. And try to observe these nightcrawlers (party people) where or to which place they are mostly spending their money. Try also to listen to these people which Lounge/bar name they oftenly mention, and for sure you will know which is the best place to go with your dancing shoes. Peace.
