Serious problem with accuracy of orders, although the staff is very amiable and the burgers are good. CHECK your sandwiches if you are ordering to-go or drive-thru! Just about half the time (18 orders total), my order has been wrong. Hard to believe, given that I always get one plain burger as a treat for my dogs. Today sadly was the last straw, as the plain burger wasn't plain, and mine included dairy, to which I'm allergic. Back to Red Robin for takeaway!
