Boston Pizza has a bad rap where I work, as greasy fast sit-down food. I'll be the first to admit it's not overly healthy and probably shouldn't be consumed on a regular basis, but sometimes one just feels like a little grease to help the bowels.. (haha I'm half kidding).
The good thing about Boston pizza is that they are fast. I've gone here in large groups and they do the pre-ordering thing, so the food is basically ready when you sit down. It's pretty efficient. They have specials everyday which are a good deal. I think the specials are $6.99 or something, and you get a good size meal off stuff on their regular menu.
Whenever I've come, I've gotten their pasta. It's really simple, but good and not at all greasy (at least not from what I can see, and that's all that matters).
