My burger was pretty good, but my girlfriend order...

My burger was pretty good, but my girlfriend ordered a wedge salad, received a veggie salad instead. They sent it back and brought the wedge salad after about 5 or 10 mins, but she noticed it had ranch instead of the blue cheese described in the menu, and no blue cheese crumbles. She asked the waitress, who went and asked the cook. Turns out they were out of blue cheese. So instead of telling her and giving her an option, they tried to sneak the ranch in and hope nobody noticed. We've liked this place in the past, but that is just disingenuous. Mistakes happen, and that's understandable, but this was premeditated, and that's a different story. We may not be back for a while. They didn't charge us for the salad, which was the right thing to do, but by then her dinner was ruined so it wasn't much consolation.
