If you look at Mr. Guppy's other reviews, it's clear he doesn't like any show on TV - why bother watching? Maybe read a book or take up knitting?
Anyway, Ginormous Food is fun to watch. Is it similar to Man Vs Food? In some ways but at least Josh Denny isn't forcing us to watch him gorge on food to the point of throwing up just to win a bumper sticker. He clearly wants the focus to be on these small-town restaurants and their signature item. As the episodes progress, Josh is clearly more comfortable and relaxed.
I'm sure many precautions and meal planning happen behind the scenes to ensure that guests in the restaurant aren't being forced to dine on Josh's pre-chewed test bites, however as the show is limited to 30 minutes, we don't get to see this due to some sort of sorcery called "editing".
Anyway, looking forward to more episodes and new seasons!
