I just discovered that you can get coupons for San Leandro restaurants at http://www.openfence.net/coupons.cfm (they also have coupons for other businesses, but this is a food blog). Featured restaurants include The Englander, Creasian and Porky's Pizza Palace (but there are quite a few more). You have to register to get the coupons, but they are free - albeit limited in number and only good for a month after you get them.

They also have a couple of restaurant coupons for Castro Valley (Buon Appetito, Palomares and a couple of other ones) and Oakland (Mezze, Tropix, La Cucina Italiana). I suspect they're working on getting more restaurants, so it'll pay to check them out before going out to eat. I know I will.
