I can't think of many places that do cheese fondue so it makes for a unique experience. Their cheese fondue has either wine or beer in it, making the taste interestingly complex. Stay away from the kettle-chips, they taste like regular chips that are warmed up. They also serve an assortment of beers.
Cheesewerks has a casual and clean atmosphere, not unlike the Ikea cafeterias. Speaking of which, they use the Ikea bowls to serve some of their food in. You go up to order, and when your order is ready they call out your name and you grab your tray of food. It's simple and it works, although I wouldn't go here for a romantic date.
The two times that I've gone to Cheesewerks have been to participate in their food trivia nights. It's a family-run business and the owner is a hardcore nerd when it comes to trivia. His enthusiasm is great and the trivia night is always well organized. There is always a food theme, and he keeps it interesting by changing up the question or challenge structure. A forewarning that the questions are really difficult and browsing for answers is not allowed! There is a fee for the trivia and the prizes are half of the collected fees and some bonus stuff.
