It is generally recommended to drink only bottled mineral water which is readily available everywhere. There are no restrictions on the sale or consumption of alcoholic drinks in Tanzania. A good selection of local beers and soft drinks are available everywhere, and you will find a range of imported wines, beers and spirits in many places, although these can be expensive.
The quality and value of food in Tanzania is highly variable, and in general, the more expensive the lodge, hotel or restaurant the better and “safer” the food will be. Eat sensibly, be wary of cold buffets and salads – particularly in the first few days of your visit.
