Restaurant ad rice, salad and one kind of meat. I dont think its a good ad, because what if somebody opens another restaurant across the street, and put this ad rice, salad and two kind of meat lol. That would be cool. What do you think?
It all depends on what the restaurant wants to put up as their special and what, if any, the competition does. It also depends on pricing, when it's two meats it's often more expensive. Anyways, why would the restaurant need to care they put one meat? There's obviously no other restaurant offering your suggested "two meats" to compete.
Two of a kind meat makes no sense. One of a kind means that it's unique. Plus if another restaurant put up an ad just to attack another restaurant, that would look stupid.
