If you are a visitor coming to Hanoi, it is likely that you will reside in Hoan Kiem District near the Old Quarter. This is where most tourism activities are, and also where most tourists would congregate. It is by far, the most convenient and safest area to stay at. And since many of the top attractions in Hanoi are located in this vicinity, it is inevitable that many of the Halal restaurants in Hanoi would be found here as well.
