There aren't many places I won't eat at; because the food was just flat out disgusting, or the service was terrible.
I don't carry for Utah Subway's, though. Believe it or not, they make their sandwiches wrong. Not only do they turn your sandwiche into a salad (grab a fork and dressing, so you can eat the droppings too), but they put the condiments on last. That way when all of the stuff falls out, you also loose your mayo and mustard. Who's brain child was that???
I've always liked Hire's from way back!
A&W used to be my favorite, before KFC turned them to crap.
Taco Time is still good, but it was WAY better ~20 years ago!
McD's used to be favorite, until they started microwaving their food and hiring kids with no respect - their service sucks at most places, at most times.
Taco Amigo is another favorite....
