As a Middle Eastern, predominately Muslim nation, Egypt is not the biggest partying and drinking destination in the world. There are a variety of clubs, discos, casinos, and bars, but it's not a huge part of the culture. That being said, Egypt is full of life, and there are many other things to do for nightly entertainment while you are in Egypt.
Coffeeshops and local hangouts in Egypt are open until the early hours of the morning serving sheesha, food, and hot beverages. Bars and clubs usually start to fill up around 10 pm, and some of them shut their doors by 2 am, while others remain open until 4 am and beyond. Egyptians like to dress smart. Even during the day, though it's often blazing hot, men usually wear long pants and shoes. When it comes to going out at night, it's important to look good.
If you are on the Red Sea, you might get away with board shorts and flip flops, but in the city long pants, loafers and sweaters are more respectable.
For women, there's an entirely different set of criteria on how to dress in Egypt. As a predominantly Muslim country, it is highly important to respect the rules and guidelines that Egypt has in place.
No, it's not a requirement for a woman to cover her head even many Egyptian women don't , but showing legs and arms is iffy. Ultimately it's up to you, but I recommend always trying to be respectful in the country you are visiting. Many nightclubs in Egypt are located within major hotels. In Cairo, the main nightclub area is around the Zamalek district. Bars exist around the country. Any establishment that serves alcohol is required to be indoors, and the windows blocked from the outside so no one can see inside.
