I have purchased a few Restaraunt.com coupons for the Disney area but none of the ones you have mentioned.
I have bought TGIF over on Sand Lake road. A bit of a drive from Disney, closer to Universal but still a bit of a drive. they have limited coupons so you have to check often for these. I have never gotten one during the sales, I always pay full price, but still pay $10 for $25 so I get $15 free. this coupon can be found under the name "Friday's" not TGIF.
I am using one in April on our ladies only trip for Barney's Steak House. That restaraunt's menu looks expensive but it will be a nice night out with the girlfriends.
There is another TGIF that participates and you can find it under the name of "Friday's sports bar" That one is over on International Drive, closer than the first I listed. I have never tried that one because I don't enjoy driving on International Drive, way too much traffic and people who don't know where they are going.
When you do a search put in the state, then the area and click on refine until you get just the Orlando area to limit the restaraunts to the ones closer to disney.
