I always was an In and Out Burger fan but BK was #2 for the regular chain stuff.
You'll have to forgive me, but being where I am, I have never had an in and out. Shoot, we just got a Chik-Fil-A this year... What is here that is national are: McDonalds, Burger King, Wendy's, Five Guys, Arbys, Pizza Hut, Dominos. Little Caesars, Taco Bell, KFC/A&W, ChikFilA, and Dairy Queen. That's my entire fast-food selection with the exception of El Sombrero, which used to be a Taco John's, and pretty much still is, without the branding (He told them to screw their franchise). Oh wait... there's a Popeyes now too (though I've never been).
And of those, the long standing ones (old enough that I don't consider them 'new') are McDonalds, Wendys, Pizza Hut, KFC/A&W, Taco Johns, and Dairy Queen, with an honorable mention to BK, who have been here off and on for about 20 years (Just not all the time). Those are the ones I grew up with.
So my experience with the more high-grade joints is limited, if not entirely absent.
The problem is that over the last few years, I can go to the same franchise store, buy a Whopper and it tastes the way I always remember. that distinctive Char Broiled flavor I love.
Then a week later at the same place, I'd get another and it tasted totally bland/plastic. I have no clue as to how they manage this as a Whopper isn't rocket surgery. Especially as 'I have it my way' every time, meaning bread, meat, lettuce, pickles, tomato and ketchup. You can't really vary the taste of that without massive increase or decrease in the actual quality level of the ingredients.
Now I would understand if it went from Good to bad or bad to good and stayed there. But it varies visit to visit and by a lot.
That's right. It is definitely noticeable between the two franchises here - More so at the south store (unfortunately, the one closest to me), and there is a marked difference in taste between that and the east store, which to it's credit, tends to maintain a more uniform consistency (except for the night shift). I have often wondered at that, much like yourself.
But, BK is way out of my way. I am on the west side, and out of town, so even though I like them best, I normally don't go there... The stuff within easy reach is Mickey-D's, Little Squeezers, and Arbys (Only because I get to say 'Horsey Sauce' and people take me seriously)... If I stretch it, the taco joints, KFC/A&W, Za Hut and DQ are all up on the north end of Main, but I can't get home with luke-warm food from there.
