My advice: don't order based on what other people think or recommend. That seems to be the critical mistake that people make when they go, which then results in disappointment when something doesn't "live up to the hype."
If another appetizer sounds better than the cheese soup, try the other appetizer. Personally I love the chipotle chicken sausage and sweet polenta; I think it's much more interesting and flavorful than the cheese soup.
On the entree side however, the filet would probably be a good choice. The burger also sounds very interesting, but I've never tried it. I would not order the prime rib sandwich again. My server recommended it, but it was like a greasy, heavy cheesesteak - not my style of food, and I barely touched it. If you pick food that sounds appealing to you, I would expect a good meal.
