It's intriguing me. Out of curiosity how exactly does it help?
Has anyone tried Buffet Go? http://www.buffet-go.com/
It's not available in all areas. There are 4 participating restaurants in my area. Basically you go the last 30 minutes (or some pre-set time period) before a buffet restaurant closes and they give you a container and you can take as much as you want for a fraction of the normal price of the buffet.
