I agree with what a lot of posters here have said. This guy didn't learn his trade on the back streets of Mumbai, he learnt them from cookbooks and forums - I'm almost certain he will have registered on CR0 at some stage. His recipes and techniques are very similar to what we were discussing here a couple of years ago. Maybe that's coincidence but there is a reason he talks about BIR style, mix powder, base gravy e.t.c. You could ask 100 proper Indian chefs what BIR means and I doubt any could answer correctly.
The videos are a good quality and there is some good narration. The Madras recipe looks okay and the base gravy is fairly standard fare. Personally I think he used too much g/g paste in the Madras and he didn't cook it out enough. I only use garlic paste in my Madras's and about half the amount he used. I cook it until it starts to brown then in go the spices and tomato dilute (much runnier than his) and cook that out too.
Finally, if you are running a curry establishment you gotta have a tandoor. Most of his food will never get above average without one.
