Hi, both!
>>If you can get down your local takeaway and hassle em for some recipes
Ah, I'm afraid I don't have the bottle of some of you guys! Though I did ask once at my (best) local takeaway if I could go in and watch my meal being cooked on a quiet night. I was told politely but firmly that "we don't do that sort of thing".
My favourite BIR meals are Chicken Vindaloo, Lamb Madras and Lamb Pathia. Chicken Dhansak too. I always have Sag as a side dish and, if I'm sharing I'll split a Sag Prawn.
But my top of the list is (here I'll get laughed off the screen) Chicken Tikka Vindaloo! Yeah, I know, I know... A friend of mine introduced me to it and it wasn't 'till I tried some of his that I believed it could work!
I only try to reproduce plain Vindaloo, Madras and occasionally Pathia at home, though.
