After eating at well over a hundred curry restaurants across Canada and the US, I thought I'd post this as "typical" for anyone who travels over here and wants a curry.

Clockwise from top right:
Chicken Tikka Masala - notice the capsicum and onion chunks. Robustly spiced, this bears little resemblance at all to BIR CTM. No sweetness, no cream, no coconut. Its more like a cross between a BIR Jalfrezi and Curryhell's North Indian Special. The chicken tikka is mostly similar to BIR though.
Pilau Rice - almost always with cumin seeds (and often way too many) this one has peas. Colourings other than turmeric aren't all that common.
King Prawn Korma - it may look like a BIR korma, but its not. Not even slightly sweet, it is a mild dish with either almond or cashew powder and cream. The absence of a sweetener and coconut makes it a very different dish to BIR. The "standard" starter curry for the less adventurous tends to be Butter Chicken.
Chicken Madras - at first glance, it could be a BIR Madras, but again, not even close. Notice the curry leaves and mustard seeds. In addition, this dish has coconut. Its actually quite a tasty curry, but I can't think of any BIR dish that I'd equate it with. I usually order it "as hot as you can make it" in order to get it close to BIR Madras heat. Only a Vindaloo over here is what I would classify as a hot(ter) curry.
The curries themselves are almost always made with a base gravy, but are more heavily spiced than BIR, but with much less chilli across the board.
The net of it is, there's some decent curry houses out there - but if you're looking for BIR you will most definitely be out of luck.
