The last few times I went, I remember there was no dollar menu, and everything there cost about a dollar more than at a regular McDonald's - in terms of the meals- like the happy meals and value meals (October, June). It is cheaper to buy a meal there than in the parks, but still more expensive than a regular McDonald's. It may have changed since then though, but I have been there even before that, and they still were a dollar more expensive (except the drinks, that is).
