The anniversary prices are available for one night only. Utah has locations in Taylorsville, and Salt Lake.
As a reminder, The Old Spaghetti Factory has coupons and special offers via their Factory Insider Facebook app. I signed up and received a coupon for a FREE slice of Mud Pie with entree purchase within minutes. The Old Spaghetti Factory also has a birthday club for kids. Sign your child up and they will get a free meal on their birthday.
