That is really annoying.
Most likely followup question: Exactly how many hours have you spent on the Taco Bell website in the past year, anyhow? Why would you spend any time there?
(If it weren't for the XBox One giveaway I'd expect the average answer to the first question to be indistinguishable from zero for everyone reading this.)
Argh, I forgot my "HN is a big website and I'm sure there's a dozen people who will pop up and say they do" disclaimer. Yes, hello down there... but you are the exceptions, and frankly I still don't believe most of you popping up to post something aren't just being contrary anyhow. (Nutritional data I'll believe, but a mobile app will be better at that anyhow! I too have tried to use websites to get nutrition info... I've only only found one that was any good at their mobile experience.) To a first approximation, nobody uses the Taco Bell website for any significant amount of time.
Google Search -> How many carbohydrates in Taco Bell 7 layer burrito -> I'm feeling lucky -> Taco Bell's website with nutritional information.
Many restaurants if you ask at the establishment do not have this information, but it is typically available through their corporate websites.
I am not going to install their app just so I can reference their data, which I guess is a win for them for hiding that information.
Maybe these are minor concerns but "app only" sounds like a half-baked MBA's new strategy.
For example someone wants a salad. What types of salads do they have? What is in them all? These questions are better resolved before you're sitting at a drive-through window.
I often access menus using a PC/web-browser. I don't currently have any establishment's custom app installed.
