When we went to Colorado, I ate at Outback Steakhouse frequently as it was one of the few restaurants that was very friendly to those with food intolerances.  I was delighted to see a $5 off coupon on their website. 

To get the coupon, you can either like them on Facebook (but that requires that you share your own and your friends’ information, which I am not comfortable with), or you can click a button to get the coupon sent to your e-mail address.  I just got mine through e-mail yesterday.  You have until 7/22 to get the coupon, and it expires at the beginning of August.  Mine expires 8/4.  Enjoy!
