One of the best biryani serving restaurant zam zam is located near park circus phool bagan near Frank Anthony Public School. I have been there as it was recommended by my friends. The experience was brilliant better than I thought. The food quality and taste is just finger licking good. The service is also very good and quick service makes its customers enjoy there food even more. Zam zam is rated one of the best restaurants because of its famous biryani but other food items are equally good.
