If you are looking for a place where they sell fresh vegetables & fruit, you can go to the whole sale market here in Doha. Opposite the Thursday/Friday souq in Al Mamoura. Going on salwa road towards Qatar Decoration roudabout. Turn left at the roundabout, next roundabout turn right & then 2nd roundabout (small) right again. It has a sort off castle like look wall/ square around it. Go inside and you will find beautiful fresh produce. Men with wheel barrows will carry your stuff to the car.
