I'm not sure any would be any good for you, I believe they are limited to only six people, and only $600 per restaurant per month. At least the ones administered with the idine program are. (of course, since the bill doesn't say how many people were eating, there isn't any way for them to enforce the only six people rule). You have to dine at a restaurant on their list, and some of them only allow one visit per month.

Knowing all those rules is important if you want it to work, otherwise if there aren't restaurants near where you are then it may not work for you.
