Just got back from Amsterdam where I ate a meal at a like a local sponsored restaurant. I reserved the meal through http://like-a-local.com/ which hooks up local hosts with people who want to meet said locals. Not only do they have local hosts who serve you in their homes, but also local host beds and outings. Great idea. Like a local is trying to expand across Europe and, finally, to the states- I'm geeked to get it going.
The site is in both Dutch and English
You can check out my review of my experience of "saskia's restaurant" (found on like a local) in Amsterdam. It is on the International board under Like a Local: Amsterdam.
