Arsalan is undoubtedly the best biryani house not only in Kolkata but in India. For mughlai type of food like Biryani, kebab, tandoori items. They also have many branches in Kolkata but I have visited the Park street branch three times and each and every time I enjoyed their food very much.
As a foodie guy I have visited many restaurants but Zeeshan and Arsalan are best and Arsenal will have a slide advantage over Zeeshan. I like the combination of Mutton Biryani, Mutton Stew, Chicken Chap, Chicken do-piazza and obviously firni. Those who are staying in Kolkata and missed Arsalan it is a crime. It is the not good it is best of all. every food has a very good quality but only one thing that the amount is little bit less than the others. So you need to spend a little bit more money than others but you will br fully satisfied.
Here you will not only biryani but also items like roomali rooti, naan, Kulcha, Variety of rice item like egg fried rice, Chicken fried rice etc. Every thing is really good but the Biryani is extremely good. So those who are staying in Kolkata must try Arsalan at once and then definitely you will go second time there to enjoy.
