Regarding the Game of Thrones cookbook, it's not bad at all. Something the show doesn't delve in much is that the books mention
a lot of food, so the makers of the book just ran with that, taking every mention of food in the books, instead of pulling recipes out of their asses or assigning common modern day food for random characters, like something dumb like "Jon Snow pancakes".
For every "exotic" dish there are a few easy to make (scrambled eggs with peppers and cheese; breakfast with bacon, hard cheese, a boiled egg; hummus, etc). I've made a few of the recipes and they're pretty good.
Also the pictures make the food seem delicious and well, actually resemble food:
