I agree with you.
Most good chefs are only too pleased to show you how good they are (just watch them on all the TV cooking programs).
IMHO the only chefs that have something to hide are the 'dirty' chefs who use unclean procedures. I have seen these is many restaurants including Indian ones.
I always think that if you are not allowed near the kitchen, especially on a quiet night like Mon, Tue, Wed then there might be more to worry about other than the smell or flavour!

I say this with some knowledge as my last role was as a project manager for a large American based catering company...... And I have been in a few BIR kitchens over the years!
