Bottled water is available everywhere. The local brands most common being Baraka, Siwa, Hayat are just as good as expensive imported options which are also available: Nestle Pure Life, Evian, Dasani bottled by Coca-Cola, and Aquafina bottled by Pepsi. A note on the local brand Baraka: while it is perfectly safe to drink this brand of bottled water, some may notice a very slight baking soda aftertaste, due to the high mineral content of its deep well water source.
No matter where you buy bottled water from even hotels are not entirely reliable, before accepting it check that there is a clear plastic seal on it and the neck ring is still attached to the cap by the breakable threads of plastic. It is common to collect empty but 'new' bottles and refill them with tap water which drinking a bottle of will make you ill. Not all brands have the clear plastic cover but all the good ones do.
restrictions on alcohol
Egyptian laws towards alcohol are officially quite liberal compared to most Islamic countries, except for the month of Ramadan when alcohol is strictly forbidden. During Ramadan only holders of foreign passports are allowed to buy alcohol, by Egyptian law. However, the enforcement of this law is by no means consistent. In tourist areas like Luxor, alcohol is sold even during Ramadan, and those who look like foreigners will not be asked to show passports or other documentation.
During Ramadan alcohol is often sold only in Western-style hotels and pubs/restaurants catering especially to foreigners. A few days of the year, as the day of the full moon the month before Ramadan, alcohol is completely banned. Also some hotels and bars catering to foreigners will stop serving alcohol during the Muslim holy month of Ramadan - phone ahead to make sure alcohol is still being served in order to avoid disappointment.
Egypt is a predominantly Muslim nation and alcoholic drinks are religiously forbidden haram - though not legally - for strictly observant Muslims. That said, Egyptians tend to adopt a relaxed and pragmatic view towards alcohol for non-Muslims and foreigners. It is tolerated by the vast majority of Egyptians and consumed by a sizable number of them. Alcoholic beverages and bottled drinks are readily available throughout the country especially in larger towns and cities, as well as tourist centers. Please note, however, that public drunkenness especially the loud and obnoxious variety is definitely not appreciated - without caution, you may end up drying out in a police cell. Try to be a good ambassador: if you must get "tipsy", confine it to the hotel or very nearby! It's actually quite rare to see drunken tourists, even in the most intense tourist areas...
