I did not find it worth it.
First, some of the restaurants, like McD's, limited what it covered, as it was only a hamburger kids meal. And, at the Pastamore, the kids meal was horrible. As it were, we also ended up at restaurants that did not accept the card. So, the card company made money on me.
I would never recommend it, and will never buy it again.
Ymmv, though, so just my opinion.
