I've been surprised to find out that Taco Bell of all places is great at getting my special orders right. I never do it at the drive thru when ordering normally, but once I got the app I tried adding extra onions to a bean burrito and it went off well.

Later I customized that new grilled cheese burrito thing they have with like 4 substitutions and was perfect. Saved it as a favorite and they got it right every time since.

And this is at the closer to my house but worst taco bell in my city. Yep, the one that was "out of beans" at 8pm on a Friday last week. They also randomly close 2 hours early for lack of staff all the time (no other fast food joint does that here, but I get it worker shortages)
