Sounds good but:
1. Is the normal output of the place a cut above average? If many of us agree we can prepare dishes which are better than the current (2009) sad average BIR standard, then it only seems worth going to a teacher who is much better than average and who bridges the 'missing 5%' taste gap. Does this place fit the bill?
2. Will we be able to draw up a 'contract' or something to help guarantee that he really is showing us the real thing, rather than some dumbed-down version, especially spoiled for our lessson? On the one hand, we wouldn't want to be too heavy and demanding but we'd need to make sure it isn't another disappointment. If the Brick Lane demos, which a few members went to, were all they'd promised to be, then we'd have had most of our questions answered. But it sounds like they didn't deliver.
