I came to know this from my friend and took time to search for as it is in a small lane.We were 4 friends and ordered Mughlai chicken.The taste was awesome with Rumali roti but the cost is too high.Well it is the taste you pay at Karims.We also ate mutton corma which also tasted good.The restaurant is world famous for Mughal cuisines and has been serving since 100 years.
Do pay a visit there if you happen to be in Old Delhi.
