Swiss Chalet was always one of the fancier chain restaurants here - at about the same level as the Keg. I'm not sure if we were just that classless or if they were different here. Now that we have ones with the new design, they're still popular but they've dropped down to, say, Boston Pizza/Jungle Jim's level.

I've had Chalet BBQ. It was a LONG time ago (I was with my parents, so probably still a teenager), but I still remember it.
