Please don't book restaurants deals with them. They have found a very neat way to cheat customers. I have been cheated twice so I know. They tie up with a restaurant which publishes lucrative deals but has no intention of honoring them.
So I purchased a Groupon for a Mediterranean restaurant. When I reached the shop I found it was closed. They had shutdown their Business but Groupon conveniently kept selling the deal. But when you ask for refund they give you only credits back. I think this is their way to show that they are generating revenue
Same thing happened to me with Italian restaurant, only difference was that they were open but not willing to accept Groupon. When I asked for refund to Groupon, they refused and only offered me credit.
This is the last time I am using this fraudulent site. Just letting other customers know what problems they might face if they take deals through Groupon.
