Shomal is my number one favourite when it comes to Persian food. Their dine in area is very nice and roomy with many private-ish areas.
The best part as well is that they do delivery!
I do it either by calling them or by using JustEat, and the km range is pretty good..
My favourite and highly recommended plates would be Sultani Kabab, and Vaziri kabab, it's always tender and juicy even with delivery.
Their rice with fava beans is great as well, and Zeytoon Parvader is A++
