Yesterday, I visited Katani it is the best Dhaba in Mohali 3b2 as their food and way of representation is really good.
I had 2 Laccha Parantha and Kadai Paneer and it was really good with pleasant fragrance of paneer.
Also I have tried Katanis Chinese Buffet which is of only Rs. 119 and it is best in class and value for money.
You get 6 types of chinese food in buffet. And you can eat unlimited. Katanis north indian buffet is also better and much cheaper than any other buffet in Mohali 3b2. And their service is really very fast.
I strongly recommend to visit Katani.
