Where is YO! Sushi?

"You can find YO! all throughout the United Kingdom, as well as in Ireland, Russia and the Middle East." Source: http://www.yosushi.com/restaurants
YO! Sushi has not spread across the world and is yet to hit its food origin country but it is slowly growing, the company has spread right across the UK with the most restaurant being located within the United Kingdom.

I'm surprised at the international locations as i would have thought that it would be more popular places such as; Rome, Madrid, Paris. The restaurants open in Russia and Kuwait seem an odd place to expand but i would like to look into that more and see what the restaurant looks like in each of these unusual countries. YO! Sushi has taken the UK by storm so i cannot see any reason for it not being able to hit Europe or the US.
