You Will Be Able to Drink Alcohol, but You May Not Drink Well
Despite Egypt's religious conservatism, alcohol is widely available, particularly in large hotels and some restaurants. Even the most modest Cairo hotels are likely to feature a rooftop bar, and while many premium cafés do not offer alcohol, the majority of restaurants do (though likely only beer and wine). The environment becomes more conservative as you go south, and when you get to Aswan, you'll likely find fewer opportunities for drinking outside of the huge hotels and their restaurants. You must, of course, pay for the privilege. Because imported alcohol of any type is pricey, you may want to try the local beers and wines instead. Three local brands are generally accessible, although additional brands are available.
Cape Bay (made in Egypt from South African grapes) is the finest of the bunch, followed by Omar Khayyam and Obelisk; any of these would suffice in a pinch, but you won't want to take any bottles home with you. Stella and Sakara are two beers that can be obtained practically anywhere and are both quite nice. You may be better off sticking to foreign gin and tonics. However, there are several no-nos. It is never okay to drink on the street. Drinkies and Cheers are two local liquor businesses that deliver. At all costs, avoid any extremely inexpensive, local hard alcohol.
