A great place to find hidden freebies is the restaurant email club. Most restaurants have an email club and regularly email coupons and freebies to members. More importantly, there is usually a great freebie just for signing up! Here are a few that I have found recently:
Sign up for the Johnny Rocket's email club and get a FREE hamburger
Sign up for WendyMail and get a FREE $1 Menu item plus $1 coupon
Sign up for Chevy's Fresh Mex email club and get a FREE appetizer
Sign up for The Melting Pot Fondue Club and get a FREE chocolate fondue for 2
Sign up for Longhorn Steakhouse email club and get a FREE appetizer
Sign up for the Texas Roadhouse email program and get a FREE appetizer
Sign up for Texas de Brazil's email club for 25% off coupon for up to 8 people
Sign up for the Chilis email club and get a FREE chips and queso
Sign up for the Macaroni Grill's email club and get a FREE appetizer
Sign up for On the Border's Club Cantina and get a FREE queso or empanadas
Sign up for the Uno's Insider Club and get a FREE appetizer
Sign up for Dairy Queen's Blizzard Fan Club and get BOGO FREE Blizzards
Sign up for the Houlihan's email club and get a FREE appetizer
Sign up for the Firehouse Subs newsletter and get FREE chips and drink with sub purchase
I think the lesson learned here is that before dining out check the restaurant's webpage to see if they have an email club for you to sign up for - you're sure to get something FREE out of it! If you know of other restaurant email club FREEBIES leave a comment or send an email!
