GuildNavigator's Vienetta posts got me to thinking about restaurants I liked but are no long with us. What are yours?
Bill Knapps- God dammit I miss Bill Knapps. The jokes about it being god's waiting room & polident on your plate aside, Bill Knapps was a good place to get a cheap but quality meal. I ate there every chance I got and even enjoyed Bing Crosby singing Happy Birthday to me when I got 24% off my check for my 24th b-day. The free Chocolate cake helped too.

Morrison's Cafeteria-
Predominant in the Southeast, Southern food served Cafeteria style and here again it was a cheap place to eat. (see a trend yet?) Blueberry muffins the size of a dinner plate and never a bad meal.
Ryan's Steakhouse.
A chain of steak & buffet restaurants. I ate here often as a kid and even met a few of the Detroit Tigers at the local Ryan's back in the 1980s. (Tigers spring training grounds are 3 blocks from where the local Ryan's used to be)
There's more but I'll let y'all add yours.
