A good idea but poorly executed. Customer service is severely lacking - don't think you can talk to anyone and it takes weeks or months for a reply.
I purchased restaurant vouchers for vacation and the restaurant was closed. I've notified restaurant.com on 4-6 occasions and the restaurant is still showing as an option (permanently closed). But I get to exchange my voucher... I won't make this mistake again. So much for their concern to make the experience good for us clients.
