The Cantina Traditional tortilla chips are made of yellow corn and are slightly smaller than standard Tostitos.
A 12-ounce bag retails for $3.29 in my area.
I can't really say I have an image of a "cantina chip" in my mind. There are a lot of Mexican restaurants in Los Angeles and the chips they serve can vary wildly. Some just put out packaged chips from a supplier, while others make them themselves. I prefer the latter over stuff that I can buy from a supermarket (actually one of my local, more ethnic supermarkets sold chips that they fried up daily... so good! Unfortunately, they recently closed to make way for new developments).
They're described as "hearty" on the bag, but they'd have to be at least twice as thick before I'd call them that. They're too salty for my liking, especially for a dipping chip. My lips started to dry out from all the salt; I got used to it after a few chips though (pretty sure that's not a good thing though).
