I went to Karim's in Old Delhi last Sunday. It being a weekend, it was really busy but the service was fast. The phirni is really awesome at Karim's. It's not too sweet and served in earthen pots and it adds to the flavour.
Chill Out With Some Phirni From Karim's In Chandni Chowk
What Makes It Awesome
What Could Be Better?
Food items should be covered better.
What's My Pro Tip?
It's best to take a rickshaw till Karim's. It's very easy to spot as it's near Jama Masjid.
One phirni is for INR 31.
