I've met Jamie and he was lovely. Also ate at both Fifteen and his restaurant at Watergate Bay a number of times and it was always fantastic.
However the Jamie's Italian sadly seemed to not have a strength - overpriced for chain restaurant food, bland, not particularly memorable food, boring food basically & no reason to return and certainly wasn't competing against Pizza Express or similar so I wasn't surprised by the news.
If he could find a way to get his 'proper' restaurant food to the masses then great, but this wasn't it - at all. Meanwhile, he'll survive I'm sure. Shame about all the job losses though.
