The previous reviewer seems fairly flummoxed by the fact that this location (and pretty much every other Wave's out there) is seemingly populated entirely by College/University people. Frankly, I think that's Waves' target demographic; many, if not all of Waves' locations are within short distance of a college campus, either by walking (as in the Coquitlam location) or driving (such as the North Vancouver location).
One also has to consider that many college/university people keep odd hours - many of them sleep in well past what most people would consider 'normal', and stay up very late to get assignments done; I should know, I only graduated six months ago myself! I suppose all I am saying is that this is really the kind of people Waves' attracts, so if you have an issue with students, don't go to a Waves'.
As to the actual coffee, it's pretty good. Given the atrocious garbage that is Starbucks, it's nice to see an alternative that is at least a little better in terms of quality. The coffee is all fair-trade and organic, which I like - I'm not the sort of person who wants to rip off others, and no doubt this policy of Waves' appeals to other socially-conscious people as well.
Service is generally quite decent - no worse than any other coffee chain I've been to, and certainly no worse. Even at three or four in the morning, the people behind the counter are pretty perky, which really helps on those all-nighters!
Food is so-so. I say so-so because 90% of it is junk - pastries, muffins, cakes - the regular coffee house stuff that will just make you fat. The nice thing, however, is that they do offer a few healthy alternatives such as salads and flax-bars, so that those of us who actually want to stay in shape don't have to suffer from nothing to eat, like we do at most coffee chains!
Overall, nice place, always open, decent ambiance. Anyone who has an issue with the demographic the franchise is almost certainly trying to appeal to, however, should probably go look for a more contemporary coffee house.
