Recipe: Not Exactly It But...

I haven't tried this but it is from Black Angus, Not Houstons. But it is a Potato Soup. Maybe it is similar?

Black Angus Potato Soup

Ingredients:
4 large baking potatoes
2/3 C. butter or margarine
2/3 C. flour
6 C. milk
3/4 tsp. salt
1/2 tsp. black pepper
1/2 tsp. white pepper
4 green onions -- chopped and divided
12 slices bacon -- cooked and crumbled
1 1/4 C. cheddar cheese -- shredded and divided
8 oz. sour cream

Preparation Instructions:
Wash, dry and prick potatoes with fork. Bake in 400-degre
oven for 1 hour or until done. Let cool. Cut into half lengthwise
and scoop out pulp; set aside. Use skins for something else, such as stuffed potato skins. Melt butter in heavy saucepan over low heat; add flour, stirring until smooth. Cook 1 minute,
stirring constantly. Gradually add milk, cook over medium heat,
stirring constantly until mixture is thickened and bubbly. Add
potato pulp, salt, pepper, 2 Tbs. green onion, half the bacon
and 1 cup cheese. Cook until thoroughly heated. Stir in sour
cream. Add extra milk if necessary for desired consistency.
Serve with remaining green onions, bacon and cheese.
