I thought I'd see what sites appeared when I typed "pleasure palace" into my internet search. Most of what appeared was to do with an American clothing company called Golf Wang! Not what I expected.
I must admit that some of Nigella's poses and innuendos do make me cringe and seem a little OTT.
She has had her share of problems, including being widowed fairly young and then having serious problems related to her marriage to Saatchi. She's also been very successful - so good luck to her. (Interestingly, it appears that she doesn't think leaving her money to her children would be good for them)
As for the kitchen in our house - my husband does nearly all the cooking, so I don't view it as my domain or special place. I do love to bake, though. My wee sewing room/study is a diferent matter. I can get lost in there for hours in my own wee world!
