I got this from http://save.lovetoknow.com/Restaurant_Coupons which is a great point:
Joining the birthday club or frequent diner’s club is a great way to get coupons and discounts from your favorite places. Join online, or ask a server at your local franchise to give you an application. A variety of restaurants offer clubs. Check out the following merchants:
- Rod Lobster
- Cold Stone Creamery
- Black Angus
- Baskin Robbins
- Friendly’s
- Longhorn Steakhouse
- Red Robin
- TGI Friday’s
- Timberlodge Steakhouse
Filling out comment cards at restaurants can also result in getting coupons in the mail. Not every restaurant does this, but it only takes a minute and can be worth it in the long run if it's part of the restaurant's promotional plan.
