Like the two women in Boston who have started up a food blog they are calling the Inn at the Crossroads. Their mission appears to be to cook up both medieval and modern versions of all the dishes mentioned in A SONG OF ICE AND FIRE.
They're already off to a great start. You can read about their adventures and get all their recipes at the Inn: http://innatthecrossroads.wordpress.com/
I have cautioned them to skip the seagull when they get to it. The rat-on-a-stick is probably worth a pass as well, and I'd be wary about the bowls o' brown served in Flea Bottom. You never know what sorts of things go in them.
Anyway, do visit their blog and give them some encouragement. They have a lot of cooking to do. Why, Joffrey's wedding feast alone featured seventy-seven courses.
Oh, and I love their motto: In the Game of Food, you win, or you wash the dishes...
