Four Weddings follows a similar style to Come Dine with Me and involves four brides/grooms attending each other's weddings and rating them on:

Dress (out of 10), Venue (out of 10), Food (out of 10), Overall Experience (out of 10)

At the end of the show, they'll discover which of the couples has won a luxury honeymoon. Viewers can also play online in the "Online wedding rater" and rate the weddings as they are shown for comparison with the rest of the public.
