i think its the anticipation of waiting for the final cast iron curry that will surely come from the couple of posters getting lessons from some real bir chefs.
Don't hold your breath! I suggest that two further conditions are necessary:
1. The "real BIR chefs" will need to come from the 1 place in 10 that (still) serves really tasty BIR food, rather than from the 9 other places which serve lesser fare.
2. The chef will need to be prepared to hand over the exact same recipes, rather than any old recipe (downgraded) which will look plausible to the punter but won't mean the chef is actually giving too much away.
