Pretty people = bad food
Tyler Cowen explains why you should avoid restaurants that are full of beautiful women:
I also start to worry if many women in a restaurant are beautiful in a trendy or stylish way. The point is not that beautiful women have bad taste in food. Instead, the problem is that they will attract a lot of men to the restaurant, whether or not the place serves excellent food. And that allows the restaurant to cut back on the quality of the food.
