I used to like Taco Bell when I was a kid, but now I think it's disgusting after always eating the food at my university. The last time I had Taco Bell was 2 or 3 years ago.
We used to go to good places to eat when we got the munchies. If the current generation goes to TB, I tremble for our civilization. But, I might buy stock in TB if pot is widely legalized...
Being from the UK where we don't have many Taco Bell's (the nearest one to me is about a 4 hour drive away) this doesn't interest me that much. However Taco bell is owned by the same company who own KFC and Pizza Hut, so I'm assuming KFC and Pizza Hut will also offer a similar app.
White Castle already has an app that supports online ordering. So on my once a year (New Years day) ordering it's easy enough to order and pay for my "meal" via PayPal and pick it up, though the first time I did it the workers in the drive thru at first didn't know what I was talking about, and it took a manager to figure it out. I love technology!
