When visiting Abu Dhabi or Dubai during Ramadan, you don’t need to fast yourself but you do need to be respectful of others who are. Think about it, if you were spending a month fasting the last thing you’d want to see is a bunch of tourists chowing down on burgers and beer right in front of you.
Because of this, it is prohibited to eat and drink in public. Some places are more lax than others, but for the most part restaurants will be closed during the day while most hotels will have private dining areas open for guests for breakfast and lunch. Alcohol is also not served until the sun goes down.
Top tip: If you’re in public and find yourself thirsty, the best option is to go into the bathroom to take a drink.
