I have, actually. I can't stand that Brian Malarkey guy. I do like Tony though. I watched a lot of his food travel shows over the years. I'm not really sold on Nigella, to be honest, but a lot of people like her. I don't know about Ludo so much.
The idea of the show has promise, although I sometimes thought that the reasoning for choosing certain contestants to be on their teams was a bit suspect. They passed on some excellent chefs and some not so good chefs were sometimes picked, although that could be more of a comment on how elite-looking chefs make quality, solid food, but it doesn't necessarily wow you and they were looking for people to wow them.
