how to earn from restaurant directory site?
 

Mainstream web site - local directory of all restaurants in the area.
I just charge yearly listing fee + featured listings. Its pretty simple website. I would like to redesign it, implement some new features and monetize it better.
Anybody have some ideas or examples of such directory websites that you frequent?
Thanks

Charge for banner spots as well. Check out menupalace.com for ideas.

Sell Restaurant.com - I just spent $150 on their site today.

I would rather implement this coupon selling myself, rather then just be an affiliate.
Keep ideas coming.
Thanks.
