People apparently do go and eat at the restaurants seen on The Chopping Block. Apparently just appearing on the show win or lose increases the number of clientele a restaurant gets. So all publicity is good publicity in this case.
The Sun Herald reveals that after Season one went to air series producers called each of the eateries that took part in the show to see how they'd been affected since.
Almost every one of the restaurants reported taking part was a very positive experience overall, with the winners noting increases of up to 70 per cent in trade, and losers up to 50 per cent increases.
So this should help them to get restaurants for season three, if Channel 9 renews it. Hopefully he will.
