It is very overpriced. A friend and I went, ordered 1 dinner salad, 1 order of fish tacos, and two sodas, and paid $50 including the tip.
I thought my salad was tasty, though no different than something you'd get at any chain place like Ruby Tuesday's or Applebees. My friend thought the fish tacos weren't good at all. He did like the rice that came with it.
Think of it as chain restaurant food, but with a hefty surcharge for the location and theming. That's really what you're paying for, the experience.
