The Blue Nile is superb. We have never had a bad meal there, it is always heaving though so booking is advised.
We have been twice to the new one on Marple road ( the old Wrights Arms) food was very good there as well.
Both of the above are enjoyable for a good night out. For takeaways and a bit of something different one evening the Shabaz as written earlier is also superb.
Unfortunately in Marple, we do not seem to have takeaway or restaurant in the same class as the 3 mentioned above.
( in my humble opinion that is)
