We've updated the menu for Taco Bell and it's interesting what has and what hasn't changed since the last update 14 months ago (January 2009.) First, most of the base menu item prices saw no movement. However, many of the value menu items that were introduced a couple of years ago have been steadily increasing in price. My beloved Beef Combo Burrito, for example, was $1.69 and is now $1.99. The 1/2lb Cheesy Bean & Rice Burrito was $0.99 last year and has jumped a staggering 100% to $1.99, all without any meat. Wow.
Also telling is the fact that the new arrivals on the value menu are very cheap to make. The Crispy Potato Soft Taco (Crispy/Soft - huh?) and the Cheese Roll-up offer super-plain, meatless menu items at 79 cents apiece.
Finally, Taco Bell is one of those places where every restaurant seems to have a completely different lineup of menu items. So, while I am sure they still exist, I do not have updated prices for things like the basic Nachos or the Burrito Supreme because they were not listed on the menu board at my local store.
