Hello xerxesvi - I'm in a similar boat. I was born in the UK but grew up in Canada. I moved back to the UK for university and fell in love with BIR food. I moved back to Canada about 10 years ago, and found cr0 about 5 years ago.
Indian food here is more traditional, and very little like BIR. Since cr0, I've come probably about 99% to the best I ever had in the UK, and people here who try it are stunned.
Dont bother looking for BIRs here - I've tried probably a hundred or so. The closest I ever found was a Bangladeshi place in Peterborough called Shafiqs.
Where are you located? I'm downtown Toronto, and can probably give you some tips on where to get some the harder-to-source ingredients.
Good luck - grab a base, and some mains from the cr0 database and get cracking.
