It is extremely difficult to use their website and App. Nothing seems to work consistently. I can only access them via iPhone, although I would prefer to use my laptop if I could. But am unable to create an account or sign-onto it if I use common laptop browsers like Google Chrome or Microsoft Edge. And they have been unable to fix the problem. Another major gripe: They list 12-15 participating restaurants in my city. Upon researching that list, I've found (so far) that two are permanently closed, and one closed but reopened under a different name which I don't see on their "list". Found one I liked. Their website showed they are alive and well. But they only open at 4 p.m. 7-days a week. No problem, but if you buy one of the certificates for this restaurant, it is only valid before 3:30 p.m. And you'd play heck getting a replacement certificate! Do your research if you use Restaurant.com.
