Restaurant reviews, and vouchers?

My moms friend when she lived in Florida found these things on the internet and they'd give her a food voucher to go and eat at that restaurant and then review the restaurant online. But as I look for them, I honestly cant find a legit one, anyone want to help out with finding a legit site? Thanks so much.Restaurant reviews, and vouchers?
Restaurant.com is kind of similar (you don't have to review the restaurant) but they sell 10 dollar gift certificates for 5 dollars and 25 dollar figt certificates for 10-15 dollars. However you should never have to pay the full price for these try retailmenot.com and type in restaurant.com to get a promo code from them to put in at checkout like right now if you type in the promo box "JOY" it will get you 80% off so that's a 1 dollar for 10 dollar gift certificates and 2 dollars for 25 dollar gift certificates. They also let you pay through paypal.com to ensure that they don't get your bank card information, but I've never had a problem with them. The only catch is that some of the restaurants require a minimum purchase so read the fine print for the specific restaurant you want to buy them for, it's great!
