Shama Biryani is a very small restaurant in sector 62 Noida, it specialises in chicken korma and biryani, both muradabadi and Hyderabadi, the place is very small and it may not be convenient to sit there to eat but you can take away and enjoy the food at you own comfort, my personal favourite is Muradabadi Biryani and I have it from there every other Saturday, it is not expensive at all, the biryani they serve is authentic unlike few other restraunts who sell pathetic biryani.
There are other chains of this restaurants but my favourite is the one located in Sector 62 Noida. Chicken Lollipop is also a must try from here.
