The name gives a clue to the menu: that's right, it's Iran's favourite lamb, potato and chickpea stew. Here they do it damn well, served with all the trimmings including fresh herb salad and a jug of the minty yoghurt drink dugh. The staff will show you how to eat it, if in doubt, and take photos of you.
It's been around for decades and the characterful interior is plastered with traditional paintings. Look for the bare brick facade and get here early or be prepared to queue.
