It's inside Souq Waqif. There's an ATM machine and Al Mandarin restaurant near Malaysian Restaurant, you walk towards the Dhow R/A side. You can see the Dhow R/A from Mandarin Restaurant or ATM Machine. It's just less than 20 meters on the left side.

If you park behind (near Diwan Amiri), there's a mosque on the parking area and it's very near it.
