It seems, @pushbutton, that your solution to most food issues at the park is to bring an external contractor in.
Now, in my opinion, the reason why you get shot down on these arguments, repeatedly, is because bringing an external mob in to run something is a cop out. The park loses control of the outlet, and can't control standards (which can be both good, and bad). They lose money - as they get less revenue when there's a competitor in the park.
If you think the food outlets in the park need improving, then by all means - put forward your suggestions. The crepe bar I quoted wasn't a horrible idea. A bit polarising perhaps as not everyone is going to want to eat crepes and the bakery stocks a variety of things sure to suit more people than crepes, but not a horrible idea to change things up.
But - when your solution involves 'bring an external in' - its a shit idea. What can the external do, that the park cannot do themselves, if they wanted to?
This is the question you should answer. Because the park CAN do anything an external can do, if they try. Chances are, they don't, because people buy the food they currently sell... And diluting their current market by opening yet another outlet at Stars just increases their costs, but won't necessarily increase their income. If the food gets to a point where people would rather eat at mcdonalds and they start losing money in their food outlets, then, and only then, will they realise a problem exists. Until then, I don't think there's much of a problem, judging purely by sales. Your review of Dirty Harry's burrito bar indicates your fussiness is probably a bit more unique to yourself than a glaring issue with a food outlet that otherwise receives mainly positive reviews.
