Customers at 1,200 McDonalds outlets throughout the UK will be able to get free wireless internet access by the end of the year.
The wireless broadband service will be provided by ISP the Cloud and will enable users to go online with their laptops, Wi-Fi-enabled mobile phones and handheld games consoles in the stores.
McDonalds previous Wi-Fi offering was a paid-for service provided by BT Openzone, which was only available in 500 restaurants nationwide.
McDonald's Restaurants chief executive Steve Easterbrook said: "The launch of free Wi-Fi in our restaurants in the UK is an exciting move that we believe will further enhance our customers' experience when they visit us."
News of the deal follows BTs deal with Fon to allow its three million broadband client base to use hundreds of thousands of hotspots free of charge.
The addition of the newly Wi-Fi broadband-enabled restaurants to the UKs network will brings the number of Wi-Fi hotspots to 11,477, of which some ten per cent will be accounted for by the fast food chains outlets.
