Not that you would know it from the page below,  but Itzik Ben-Gan is back in London to do a 5 day training course, start 03october.

Why QA are not screaming this from the rafters, I will never be able to fathom.  Its kind of like going for a physics course and finding that Steven Hawking is taking the class. Training budgets are tight at the moment and £2500+ is a fair amount to pay but ,as the saying goes,  but if you pay peanuts you get monkeys.

 Looks like you will need to be quick , the site is saying "Fewer than 5 places available".
