I'm in a holding pattern. I'm keeping them at 5 stars.
With the remodel of the restaurants and parts of the casino, the buffet is no longer open for lunch, except for the Sunday brunch.
It is now mostly a dinner buffet and is called "Pavillon 67 - Buffet Gourmand." Ooh-la-la. It is priced accordingly. That is, $26.95 CDN today translates to $25.25 in U.S. coin, pre-tax and tip. When you see the pictures of the remodel, you will understand that they had to pay for that somehow.

However, if this is truly a gourmet buffet, then it will be worth it. The lady on the phone reassured me that the quality was top-notch and it's sort of hard not to believe a lady from Montreal with a cool accent. Let's see.
