Not only that, but the coupon is good for about 10 days, so you don't actually have to use it ON your birthday. The entrees there are about $10-15, and the desserts are around $7, so this is a pretty good gift! You also get a 15% off coupon just for signing up.
So, since I like food ("and the Understatement of the Year award goes to....") and I think it tastes even better when it's free, I decided to see what other businesses want to give me gifts. This is a pretty good list of all the restaurants and even some retail stores that send you a little (or a big) something on your birthday. I think I just might sign up for all of them and see just how much free cake and ice cream I can eat in one day!
