Royal Tandoori for me too, have tried other places over the years but none come close

Another vote for Cinnamon (Kafe La, as was) - Perry Vale.

You absolutely have to try Barakah in Sydenham. We have tried many over the years (including some of those mentioned already) but this was the first we really enjoyed, amazing stand out food. Needless to say we never use anything else now.

I like the Elachi although I've only ever eaten in there.

We visited India Gate on London Road again last night, and I have to say once more that its really worth a try.
The food isn't greasy, the spices fresh and we have NEVER ever had a duff meal from there.
Having visited a few of the restaurants mentioned here I really do find it far superior.
They do takeaways as well.
