I just had one, about half a pound of beef and lettuice, onions, tomato, pickels, and a big bun.
It costs $3.95, but Hardees calls it the six dollar burger because it costs six dollars at fancy resteraunts. It was good, tasted great. My wife said when she tried it that the tomato wasn't fresh. But your milage may vary based on the way the hardees you visit is run or supplies on hand.
