Club beer is the staple drink, served everywhere. Local gin is also available but should be drunk with caution. In the countryside the adventurous can try the local palm wine. The fresh is sweet but ferments over time days and grows stronger and more bitter. Usually the palm wine equals a light beer in alcohol content, however there is no guarantee of purity or quality.
Bagged water is sold on most street corners. While it is supposed to be filtered and safe, it is not guaranteed to be. Stick with bottled water to be sure. You can buy bottled water at any supermarket, restaurant, or at the Total gas stations.
