In the late-'70s and into the '80s, dad and I would go to a chain restaurant and he would order the ‘British burger’. It was just a cheeseburger, but it had two pieces of bacon arranged in a cross like the British flag.
Was it Denny’s? Bob’s Big Boy?
Maybe Hardees?
We didn’t have Hardee’s in California. It’s called Carl’s Jr there.
But no, this was a sit-down restaurant.
The closest I can find is that a restaurant in Saint Petersburg, Florida has a food item called a British burger:
And, in the '70s and '80s, the two were completely unrelated chains. They didn’t merge until 1997.
There’s also one at HB Jones in Elmhurst, IL.

I’m still trying to figure out how you can arrange two pieces of bacon into something resembling the Union Jack. Wouldn’t you need four?
In the 70s, the epitome of “British burgers” was Wimpy, which isn’t something I would recommend to anybody.
I forget: What was the sit-down “family restaurant” Elizabeth Moss was flogging in Mad Men?
Did they have something on the menu called “The British Burger”?
Quite possibly, back then. Memory is fleeting and the old menus aren’t online.
I presume they wanted to make a bacon-cheeseburger and someone thought the crossed bacon resembled the flag.
I’ve never seen Mad Men.
All I remember is that they were at one time very popular. Country Kitchen, maybe?
Linky no worky. 
Was it Howard Johnsons? They figured into a few episodes.
Huh. Works for me. Here’s the page it’s on. (Note: They also have a chili size.)

Link didn’t work for me, either.
The coffee shop in the Petroleum Building near DTLA had a Canadian burger which was essentially a cheeseburger with a slice of Canadian bacon, and it was so good. It was also appropriate because the owners were French Canadian.
Most excellent Google Fu, dude!
Nope, not HoJo’s. I’d remember that because I ate there a lot when I was with my dad.
