Interestingly, that's actually a rather unclear question. There are (at least) two fast food franchises that bear the name "Taco Time".
The largest Taco Time is an international chain of restaurants, found in the US and Canada[0].
The smaller Taco Time, officially Taco Time Northwest is a franchise local to Washington State, largely the greater Seattle area, where I grew up[1].
Taco Time NW has generally higher quality food than most other fast food restaurants, and seems "higher end". I always really enjoyed going there, and when I moved I was surprised to find these other places named "Taco Time" that were really different.
Oh for... Thanks. I was born in southwest Washington and spent much of my life living or visiting family up and down pretty much the entire I-5 corridor. You've just solved a long-standing mystery.
That said, anyone craving Taco Bell while in the Portland/Vancouver area would still be well-advised to check out a local Taco Time instead -- it's still better quality food. Or at least it was 10-15 years ago.
It's really strange to hear you describe one as inferior when they barely sell the same food. True, they both sell food based around Mexican staples of corn, beans, tomatoes, spices, and meat, but that's as far as the similarities go.
That's weird that they are in malls in Canada (and considered inferior). They are considered a "higher end" fast food than Taco Bell where I am in the US.
