Don't follow the international board much these days, so if this has been discussed before, just ignore.
Searching for something else, I came across a website for Waiter on Wheels in Limassol, Cyprus (link below).
It also seems there is a WOW in Japan and possibly Germany.
From what I saw, they will deliver to airports as well as homes and hotels.
Well, that seems kind of cool if you get stuck at some airport and don't want the hassle of trying to get to town to get a decent meal.
Also, somethimes after a long flight, it would be nice to know you have options other than room service.
There doesn't seem to be any central WOW sight that lists the sevice internattionally. In fact, there isn't even a US site that I could find. I was surprise there were WOW's from Maine to Florida through California.
Now, this info isnt meant to circumvent any Chowish explorations in foreign lands, but sometimes you are traveling on business and work doesn't always allow you to explore a cities culinary offerings. I remember a week I lived practically on Saltines because I was in the office at 5am and getting back after midnight. WOW would have been nice.
I wonder what other countries they service?
Here's some info about the Delhi WOW
