In Reykjavík the night usually starts out slow but around midnight most places are packed with people. At some places jeans and sneakers aren’t allowed, so it’s better to dress generally smart just to be safe. Some bars are listed as restaurants but you can always drink without eating. On weekends it can be difficult to get into some of the hottest nightclubs after midnight or later because Icelanders go out quite late to the nightclubs. A popular option is to use nightlife guides. Nightlife guides offer a great service, no waiting in line and even cheaper drinks, you pay a little and it might get you a lot. Clubs and Bars stay open till 1 am on weekdays but are open till 5 am or later on weekends. Saturdays are normally most popular nights in Reykjavik to go to clubs and bars.
