This is a place where I have been a frequent visitor since my college days. If you eat beef, then certainly you would love this place. Before I go to the food part, I would like to mention that this is no fancy restaurant, its just a place where people come to fill their belly with tasty food at cheap rate. Coming to the food part, I love their tikia and paratha, you can even combine paratha with kabab, either way its just awesome. During lunch time I normally eat their Biryani with champ. The champ is very rich and full of flavor. They also serve dal gosht, which taste good with both rice or tandoori roti. Other good item in their menu are Beef stew, bhuna, firni.
Speaking of ambience, I am sorry to say there is none. There is always rush of people over there. You just get a seat enjoy their food and get out, thats it.
Customer service - the waiters dont have any dress code but they will serve you well, thats for sure.
If you speak about value for money, then Ill say the place is a real winner. You can easily overflow your tummy over here within 200 bucks as of 2018.
Last, I would say dont go by the look of the place, just try it once and I am sure you will like their food.
