The 7oz Filet Mignon with maple bbq sauce is outstanding. I usually as for the yukon Gold potatoes instead of the mashed potatoes, but if you prefer mashed, my wife says they are very good. My son has the New York strip every time we go.
I'm not a big fan of cheese soup, but people we know who are say the Cheddar Cheese soup is very good also.
If you are going for lunch, the Filet is good, the Beef Tenderloin tips are quite good, and the Vancouver Chicken Sandwich is very tasty also.
If you've never been there before, it will quickly become one of your favorites. We eat there every time we go to WDW. It's quiet and relaxed and you don't even know you're at Disney.
And the bread sticks they serve are great. Hope this helps.
