I don’t think that person is right. If you’re price sensitive and don’t just look at the default [combo] prices then Taco Bell is still elite and known for giving you cheap ways to get calories.
They always have a combo that’s cheap and rotates monthly. And like you said they have a few cheap value food like Bean and rice burrito which is also one of my staples.
Also you’re supposed to use the apps if you’re price sensitive. I work outside all day and couch surf without access to a kitchen. I never look at the actual menu of any place if there’s an app available. Apps also let you see prices between different locations.
However almost everyone I see go to any place in the real world is always buying stuff just looking at the default menu prices.
