All i know their burger is 10 times testier than crappy mac burgers http://news.yahoo.com/s/ap/20060201/ap_on_bi_ge/burger_king_ipo
The main thing holding back Burger King are those crappy ass fries... c'mon has any BK management tasted those bloated puffs of grease?
You might want to take a look at Jack in the Box. They own the Q'doba mexican restaurant chain which is very similar to CMG, but half the size. With CMG approaching a 3 billion mkt cap, JBX's total market cap including their burger chain at only 1.4 B, looks compelling.
