SHORT and UPDATED as seems to be a great idea and my mailbox is exploding:))
My husband and me would like to organize something similar to the Perfect Dinner show running on the TV. Here is the way we did it in the past: a few couples (singles are welcome, too!) met up for a dinner cooked by a hosting couple. After eating and drinking and having hell of a good time, we took a globe and made a blind selection of the country which defined our next dinner. Drop me a line or two (private message) if this sounds interesting to you and you'd like to participate AND host. Let me know if you come alone or with a partner + if you have any food allergies.
