It was way more than 6 years ago I believe. I remember when we changed over to 'keep with the fad' we were also one of the best, if not the best AYCE in Vancouver, but because we were serving higher quality and higher grade food with more professional (and freakin' expensive) Japanese chefs it was difficult to sustain and make profit and potential was very limited so we had to discontinue the AYCE. A year or so after we switched back to authentic, traditional dining.
Wakaru? 
Oh and
no, it was
never "Buffet get-your-own-food style" lol!
