This was a little difficult to find, but well worth the trip. As a big fish and chips fan, this is one of the best I've had. Also discovered a great drink IRN BRU, from GB.
This is a foodcart, so it might not qualify for your purposes, but this was the best Fish and Chips I have ever had. And I've had fish and chips is over 12 counties. I was so impressed, I had to try to get him listed here.
