Algeria produces a selection of wine (not in big volume in more) and also beer. However, Algeria is a Muslim country, and you do not find alcohol sold everywhere, you have to know where to find it.
Traditional Algerian food shows the historic influences of Berber, Arab, Turkish, and French tastes. It can be mild or very spicy and many flavoring are used. Algiers and popular coastal towns have a fair selection of good restaurants, serving mainly French and Italian-style food, though even classic dishes will have an unmistakable Algerian quality. Fish dishes are exceptionally good.
