We still have a couple of them around in the upper midwest. We also have their knockoff version Ponderosa as well.
Ponderosa and Bonanza are owned by the same company.
I got my R&I Mag with the top 400 Restaurant chains in the U.S. for 2006 based on sales and locations.
Top 10: (#) = Last year
1. McDonalds (1)Sales: $56.7 Billion / Locations 31,667
2. KFC (2) S: $14.2 Billion / L: 14,258
3. Burger King (3) S: $12.4 Billion / L: 11,129

Also of note, Wendy's is really getting hyped up for the wider launch of their Breakfast Menu in early 2008, with some stores already offering breakfast now.
If anyone wants to know where a particular chain restaurant is on the list (probably needs more than 20 locations although there are a few with less) just ask..
