Coffee & Drink in Ajman
Alcohol is allowed in Ajman and is available easily at hotels and restaurants.
Tap water is considered ok but it has a slightly salted taste. The obvious reason is that desalination plants are used to provide tap water. More to the point, you can safely use it to brush your teeth and prepare tea.
Bottled water is also available in any store around town.
The famous "Hole In The Wall" - located next to the Kempinski Hotel Ajman - was one of the few liquor shops in Ajman. Now moved down the street near the Beach Resort. It is NOT closed.
