Water Tap water is not safe to drink and ice cubes should be avoided. Bottled water is widely available but not always safe as there are some illicit brands of (claimed-to-be) mineral water from street vendors with no-guarantee that they are any better than tap water. Some approved and safe to drink brands include Aqua, Ades, Vit and Oasis. Ice cubes/bits from street vendors or small restaurants are sometimes made from un-boiled water, or crushed from ice blocks used for coolers. Those with weak stomachs are better off sticking with cold drinks from fridge.
