Over the last year, more than half a million diners in Australia have used a service that will give them a $50 voucher at any of the 1500 participating restaurants and cafes when they book eight times through the service.

The "Book 8 times, Eat On The House" program has Dimmi Rewards and is done through the Dimmi instant online reservation service. 

The Restaraunts and cafes are across the country and includes many well known and popular names.

Stevan Premutico, founder of Dimmi said,“Our latest addition of the Rewards program is part of us showing our thanks to Dimmi users and we have some exciting plans to continue delighting members for their support. Dimmi is creating a dining community of true food lovers, the Rewards program is just the beginning of us ‘sharing the Dimmi love.”

You simply need to join the program through www.dimmi.com.au and if not sure where to eat check the list of participating businesses. The site also has reviews by well know critics and other diners.

You book using the same website and after eight bookings, you will receive your $50 voucher.

It is expected that in 2011, Australians will spend around $10.2 billion on dining out (according to IBIS Research), so this is a great opportunity to get meals for free.
