This place is legendary and on a Saturday night the queue for a table snakes around the restaurant, but don't be put off the wait is worth it. And no matter how long the queue you'll be seated quickly.
The staff are always really friendly and welcoming and the food is a great example of Pakistani food. In fact I spent about a month living off the chicken tikka and karahi chicken. I live nowhere near there anymore but its worth the journey across town.
And where else can two people stuff themselves with great food for under £15.
