One of the few shows I like that is overtly based on promoting goods is
The Phantom Gourmet. I don't know the Boston area very well, and one of the few things I like to go out for is food, so it is one of the rare cases where advertising actually gives wanted & useful information.
So anyway, to further serve as a shill (sorry), today's show mentioned
The Burrito Blog. I mention it here because (besides being a wacky premise) it has write-ups on about two-dozen Mexican restaurants in Massachusetts. Goodness knows how hard it is to find a good Mexican restaurant, so I'm just trying to help. =)
