Boston Pizza is like most big chains, reliably average. The service will be decent, the food will be decent, there aren't likely to be big surprises in either direction. They are fairly kid-friendly in most locales, which is a good thing if you're a parent.
I can't honestly recommend you go out of your way to this Boston Pizza or any Boston Pizza, but if you live near here, there's a reasonable chance that you'll end up going here anyway.
