We've had dinner there twice and really enjoyed the food and the character interaction. My guess is that the cold buffet is the same at lunch and dinner... warm crusty rolls, green salad, potato salad, chicken salad, a very good shrimp salad, cheeses and salami, poached salmon with a lemon aioli, smoked salmon, smoked trout, with a couple of regional specialties (a caramel colored goat cheese, some herring, beet and apple salad) available as well.
The fish entrees at dinner were delicious - we had both the Mahi Mahi and the salmon - as was the vegetarian pasta dish. Mixed reviews on the dumpling/meatball dish. Wouldn't have been my choice and the person in our party who ordered it didn't love it.
Just took a peek at the lunch menu...I'd go with the salmon sandwich or the mushroom stuffed pasta. The pasta is the same as that on the dinner menu and it is quite good.
Also, I believe this is technically an "all you care to enjoy" meal... though they don't tell you this. If you order something and don't care for it, ask for something else instead. And they will fix something special for a picky eater if you ask.
