The choice of beers on offer in Dakar is slim; it's usually Flag or La Gazelle. I recommend the latter of the two which comes in one size: a large 63cl bottle. This is the beer I most enjoy in Senegal because of the label with a gazelle on it and the green bottle. The ABV% is 4.2%, pretty low, which is best for hot days when you need to stay hydrated. Best of all, the cost is budget-friendly at 1500 CFA or $3 (the same price of a 33cl of Flag, the other Senegalese beer). You can find recycled art wares made with the caps of the Flag and La Gazelle beer brands at the various markets around the city. Buyer beware: make sure to bring your bargaining skills, or just save your bottle caps to construct your own art souvenir.
