Speaking as a true Yorkshireman, just having returned from LA, I think there are a few myths on both sides of the Atllantic that need addressing. Firstly, the food in Tustin was too varied to comment on, all I can say is America is everything but burgers and waffles only. I too visited the King's Head in Santa Monica which did serve decent basic 'pub grub' as we call it. I was horrified to read on the menu that Britain's most popular dish was Chicken Tikka Masala. Because of the many cultural changes in our country, there seems to be a renaissance in traditional English food.
Please look up the menus for these two pubs in the north of England which give a good reflection of food available across the country.
The Queen's Head Hotel, Troutbeck, Cumbria.
The Star Inn, Harome, North Yorkshire

Last but not least, Fish & Chips is in fact Jewish, sorry to disappoint you.
