There are some great deals on this site/app. I've used many restaurant.com deals successfully but a few months ago I went to try to use one and the owner for the restaurant said they don't accept them and didn't give restaurant.com permission to create them. I emailed restaurant.com about it 5 times and received no reply. Their app is incredibly glitchy and even their site doesn't work when I try to complete transactions sometimes. If you can get restaurant.com to work, it will usually produce good results but if you have a problem, you're on your own. Great deals, HORRIBLE customer service.
