I use spotluck too and it is great! http://spotluck.com/

For Bethesda/Rockville there's a new local app called spotluck that has signed up about a dozen restaurants and you get anywhere from 10-25% off every day.

Sunday paper?
Not unless you want to dine exclusively at the likes of Ruby Tuesday.

I keep a whole alphabetized folder of my restaurant coupons. Like pp, I use Groupon, Living Social, Restaurant.com, and others including: 8 Coupons, Entertainment Book, Travelzoo, and Goldstar.

Some smarty pants said the Sunday paper. That is just wrong. Maybe you'll find a coupon for $5 off Uno's but I'm assuming that's not what you're after OP.

groupon, livingsocial, restaurant.com

It's called a Sunday newspaper.

Darn, you better tip well.

Sign up for the mailing list/loyalty club for your favorite ones. Even some good local places have them.

I don't see many restaurant coupons for places other than chains. Try Groupon for decent places.

Best place to get restaurant coupons? I like to treat myself on weekends. Mon-Fri I'm on a strict diet- or more to say, healthy lifestyle.
