I've been there for breakfast, I thought it was great. Yes, overpriced, but less than lunch and dinner (and the portions were HUGE- a good place to share a plate) Esp. the Pie of the Viper.
We went right when they opened (either 30 or 60 minutes before the park opens, I forget exactly) and it was also so much quieter, because it just wasn't crowded at all. I don't know if that was a fluke, but it was great.
