Come have a look at this website. It's done up by a couple of my colleagues, and it contains recommendations of places to eat in different parts of the world.

Still a work in progress, since the website is still new, so check back once in awhile. It would have been better if they could have grouped the posts according to region, but i'm not doing any work so I can't complain

It's a blogspot, so it reads like a blog.
Most, not all, of these places have been tried and tasted by many of our different colleagues and friends (myself included), not just the blogger, so you can be assured that the general consensus is one of approval.
Here are some highlights:
Seafood and T-bone's from Cape Town.
Samkyobsal is from Seoul.
The ramen's from Osaka.
The unagi is from Narita.
The sushi's from Narita as well. Note the size of the fish in relation to the rice beneath. Yes, that little bump in the middle is the rice. That's why we call it the Mother of all sushi.
