I found another one of those strange chip flavors recently.
As always, each flavor in the Doritos Royal line lasts about one to two weeks before it disappears from shelves, to be replaced by something else. Recently, I also saw a taco-flavored chip and tried the "very spicy" taco flavor. Yes, two taco versions. The spicy flavor was just like a well-filled taco, with a decent kick.
More soon... once I get more photos organized and uploaded!
