Mike Roberts was President of McDonald's USA until 2006. After resigning he moved
forward with his theory that Americans were ready for a "healthier" restaurant menu.
LYFE Kitchen was launched with one store in Palo Alto CA growing to 15 locations
scattered around the country. The chain went through various ownership structures and Roberts was bought out/forced out somewhere along the way.
Most of the locations have since closed leaving three LYFE Kitchens operating in Chicago.
The owner says they are doing great but who knows?
Proving once again that the market for "healthier" restaurant food is largely a mirage.
