People in kolkata and the tourist who comes to this city has a facination of having a chinese lunch or dinner in china town. It is one of the best place to have chinese food in kokata but definitely not in kafulok.
I have been there quite a few times with my friends and no matter what I order for a starter they give me the same dish. The price of the food in kafulok is comparitively high when compared to other resturants in china town and the quality of food is not so good.
Apart from that if you are going by car then you are onin deep trouble because you wont get a proper parking place over there as you will get in other resturants of china town. The hospitality is also average. Its better to go to the other resturants in china town than going to kafulok.
