The prices are good, especially during Ramadan, there are many discounts. A big plus is that there is a souvenir department, at very good prices, magnets, towers and much more. We mostly bought in Lu Lu, and souvenirs and some small things are here. I recommend you to visit. By the way, there is a luggage storage at the entrance, which is very convenient.
The prices are good, but the choice is much worse than in lu lu nearby. You can only come by taxi, forget about hiking in Dibba, the city is absolutely not adapted for pedestrians, it's hell.
