There's a Salim all the way down the same road a bit more hidden away that is actually run by this managers brother but make no mistake this small local restaurant is the original and first of them.
It's on the most visible end of Turnpike Lane opposite a Wetherspoons and near a few other good local eateries like Jashan (another Indian). But this Indian/Pakistani restaurant serves for me anyway better portions that it's sister restaurant. You can sit in but a lot of locals come, some from a bit more afar (even police officers have stopped off a few times when I popped in) to get a takeaway.
There are a few things good, but the one thing it does best is the lamb curry. I get it every time. The 5 stars are for that and that alone. Other meat dishes bring it down to a 3/4. the veg dishes i usually get are Okra, or Potato/Spinach which are very nice. A good box of the lamb curry though and a naan bread (had better naan's in all honesty, but still good) to mop it up. You get a free little salad with it and some mint yogurt too. And it's cheap.
Oh and like most who value authentic it maintains its spiciness. I hate when places cater for western tastebuds. If it's meant to be spicy, keep it spicy. This is hot but not burn your mouth stuff. Just enough to want more and tasty more importantly. read more
