A comment by Abu Dhabi Daily Photograph got me to go back to Karama to visit the Karama market. It's apparently a very infamous market, known for it's fake branded goods. You can get it all. From Omega watches to Cross pens and from Man U shirts to Gucci shoes. All for a fraction of the cost.
Some of the things I bargained for (but didn't buy) are a Breitling watch for AED 250/- and a Cross pen for AED 49/-. Remember to look out for the shady salesman who will approach you to show you the éxclusive' stuff.
