If there's one way I know I'm going to find a restaurant annoying it's that they're proud of their sweet potato fries. If you think sweet potato fries taste better than french fries, you've been brainwashed.
And are they yams, are they not? Something shady going on here. And speaking of yams, if you're tempted to add marshmallows to a thing to make it more palatable, that thing is garbage.
