Thanks guys, very interesting comments as my first thought when I sampled the dish at the restaurant before taking it home, was that it would be great with prawns and/or fish, something I commented on. So that takes care of the Sri Lankan bit.

I kept back a fair bit of the sauce as it really was quite hot and I wasn't going to eat it all. I've taken a pic (below) and had a good nose at the sauce. As you'll see from the pic, it looks quite grainy which is probably due to two reasons; the coconut which i'm sure is flour not milk powder and curdling from the use of cream and lemon juice. I think you'll agree that this dish hasn't seen any tomato puree. Looking closely, you can see a hint of red in the oil which probably comes from the chilli powder. The sauce clung to the meat (chicken) but was loose not claggy.
Taste wise it was the hot end of madras if not slightly hotter. It wasn't sweet (I had asked if they added sugar and, if so, to omit it) but you could taste the coconut and whilst I couldn't pick up the lemon per se, I knew it was there. The aroma this morning had a feint hint of BIR about it and a real depth of vegetable, which leads me to think that the green flecks are coriander rather than methi, though their pale green colour would suggest the latter, any thoughts? Also that it is more likely cooked with little other influence to the dish relying mostly on the base and the afore mentioned ingredients.
I shall be cooking the sauce tonight and reducing it a little. To which i'll add the remaining prawns I bought for the omelette, maybe some cashew nuts and serve it with the left over mushroom jeera rice and a chapati, no doubt with more pics to follow.
