I LOVE RED ROBIN. I love their bottomless fries, and feel like I get a good deal when going there. I usually fill up on fries and take my burger home as leftovers :).
If you sign up for their email list (click HERE) you get a free gift for signing up (I got $3 off my next purchase) and you get a free burger on your birthday! Might as well!
Enjoy, and happy savings to you :)
