Alcohol is permitted in Dubai and can be purchased at the Duty Free Shop on the way into the country. The limit for this is four bottles each per person. Alcohol cannot be purchased in supermarkets or liquor stores here unless you are a resident with an alcohol license. However, alcohol is readily available in all hotels, bars, nightclubs and restaurants affiliated with hotels.
Alcohol is not permitted to be consumed on the streets and there is a zero tolerance on drinking and driving. There are also some public holidays or periods of mourning where alcohol will not be served in public places. If this is important to you please check before booking your holiday if your dates are affected by these restrictions.
