I've use Restaurant.com a couple times now and no issues. I pay $10 for a $25 certificates (sometimes restaruant.com runs specials for cheaper). Usually the only fine print is a $50 minimum, which I understand and have no issue meeting with my family. I redeem right off my phone and have always been welcomed. Nice for me to get a little discount and nice for the restaurant because I seek them out and I spend a bit more than the minimum.
