The best tikka and sheesh kebab are from RAEES TIKKA in Hathi Chowk, Rawalpindi. I've been eating since I was 10 years old. It's a family business since 1950's. Before the shop was in Babu Mohalla. MUST GO. You will forget all others in ISB/RWP.
Best Samosa's at Lahori Samosa at College road (china market road) Rawalpindi. They give with channa's. You won't that taste anywhere in ISB/RWP. Its opposite Savor food, a bit further.
Shawarma at refreshment center.
Jilani's halwa puri in Lalkurti.
In Lahore, nothing matches the taste of Salt n Pepper. Been eating since they were on Mall road.
In Karachi, nothing matches the taste of Haleem at Karachi haleem, Burns road and Bihari kebabs also at Burns road. Seafood at Boat basin. Fine dining too many to list here. nice ones at Zamzama.
