The Balti is a style of curry, Balti houses & styles of curry are available all over Britain, so I believe that Birmingham part comes into it as the creative home of that curry.
Although tomato based, they usually come as either a Lamb or Chicken dish and as they are not to 'hot' you get to taste all the various spices that are in the dish.
Would I reccomend - oh yes, definitely :o)
