It'll be interesting to see if they can create anything that really makes me accept fast food breakfast beyond "oh shit it's 9AM and I need to do x, might as well get some food first..." moments. And those moments are dominated by McDonalds for me. I get the big breakfast with pancakes, eggs, etc. I wouldn't call it good outside of the hash browns which I really like, but it does the job. Personally I'm not a breakfast person, I really only cook it during football season (I'll make pancakes, eggs, and hash browns before the Lions' 1PM or even 4PM game lol). I don't have a bunch of time to get breakfast in the mornings outside of the moments described earlier. I'm sure Taco Bell could make something that could convince me to switch things up, but they have to think out the box a bit.
I tried Taco Bell's breakfast because I like to try nearly every new fast food item at least once. The AM Crunch, burrito, waffle taco...solid but nothing to write home about.
